Containment

Lids, gaskets, O-ring glands, drip edges, cable glands, hose barbs and valves — keeping water, air and dust where they belong. Every model draws its leak path: the route water would take if the seal were absent, cut where the seal crosses it. Nothing on this shelf has been pressure-tested; each page says what its numbers are and are not.

• C5-17Shinyerpan adapter, 304 SS: G1/4 female × ¼″ NPT male, with washers. One body, two seals (farm boom record, ordered 2026-07-28).

  Spray mix crossing from the NPT gauge port into the G1/4 sensor.

• C5-18Worm-drive band clamp, Ideal / Tridon family. Series number not re-read. The closer for C5-03.

  Not a vessel. It keeps spray mix inside the hose.

• C5-19Double-ended hose mender, same Banjo-style barb both ends. Repair of a cut section hose.

  Spray mix, inside→out.

• C5-20Cam & groove, thread pair: Type A male adapter × female NPT, Type D female coupler × female NPT. Same standard, from memory.

  Same fluid, into an NPT port such as a valve or a tank.

• C5-21Cam & groove dust cap, Type DC (female cap over a male adapter). Same letter memory.

  Rain, dust, and leftover spray. Cap keeps weather out of an open line.

• C5-22Banjo-style manifold flange: two polypropylene faces, elastomer gasket, stainless clamp. SKU not re-read. Size I chose: ¾″, from C5-01, not from a stated hose ID.

  Spray mix in a full-port boom joint, air outside.

• C5-23Bauer-style lever coupling (HK memory); general irrigation-hose and 6″ line variants, coupling type unselected

  Water (irrigation), inside→out. Not the spray boom.

• C5-24Barbed insert adapter for IPS polyethylene laterals, two clamps. US ag insert family; brand not selected. Frost mainlines are named and unbuilt.

  Water for frost sprinkling, inside the PE tube.

• C5-25Dixon King-style combination nipple plus a double-bolt spiral clamp (Dixon Boss family). Memory, catalog not opened. Suction side of the Hypro 9303S-HM1C. Inlet size not stated — I did not guess it. Pump itself is out of scope.

  Spray mix or water under suction. Air outside trying to get in.

• C6-01Nozzle-tip gasket seat; TeeJet AIXR11003 air-induction flat fan and cap; QJ363C body reference, cap drawing not opened

  Spray mix through the tip; air is supposed to enter the venturi. Liquid must not leave the air holes.

• C6-02Anti-drip diaphragm seat; TeeJet ChemSaver-style reference; inclusion in QJ363C unconfirmed

  Spray mix. Stops drip when a section is shut.

• C6-03Quarter-turn floating ball-valve seats; Banjo-style polypropylene; manual section-valve assignment unconfirmed

  Spray mix, section on or off.

• C6-04Ball check seat and cage; Parker check-valve reference; bought ball, cone geometry unverified

  Water or spray mix. Directional.

• C6-05Pinch-tube shutoff; Bio-Chem Valve reference; bought vinyl/silicone tube, small sample/tank line only

  Water inside the tube.

• C6-06Float-operated plunger/washer inlet seat; Kerick-style trough valve, Hudson reference; small-tank assignment speculative

  Water, inlet shut when the tank is full.

• C6-07Pressure-compensating emitter diaphragm; Netafim PCJ-style button, section not opened; catalogue example, not farm drip selection

  Water, metered, air outside.

• C6-08Hinged-flap check / suction foot valve; Hypro-style polypropylene, Hayward swing-check reference; pump named, foot valve unconfirmed

  Spray mix or water, suction. Keeps the line full.

  Water reverse-flow

• C6-10Duckbill check cartridge; Vernay reference

  Water reverse-flow

• C6-11Umbrella check seat; Vernay reference

  Water inside

• C6-14Labyrinth emitter insert; Netafim emitter reference

  Water inside

  Water inside; suction branch

• C6-16Manifold cross-port blank; Banjo manifold reference

  Water inside

• C6-17TeeJet QJ363C triple-head body. Named in farm boom record. Internal seal drawing not opened. I am not treating the "C" as proof of a diaphragm check (that is C6-02).

  Spray mix, one indexed head live, two shut, air outside.

• C6-18Backpack trigger shutoff. Brand not stated. Solo, Chapin, and Field King appear only as examples of a second sprayer, not as the unit on hand. Mechanism I chose: spring plunger, soft seat.

  Spray mix: glyphosate potassium salt, clopyralid MEA, AMS plus surfactant (farm backpack record). Not fuel.

• C6-19Banjo-style polypropylene bypass regulator. Model not re-read and not in the boom file. I added it because a centrifugal held near ~55 PSI needs a bypass; that is my inference.

  Spray mix. Bypass returns to the tank.

• C6-20Mazzei-style venturi injector with a suction-port check. Model and motive PSI not re-read. Fertigation is a planned job; no injector is named (farm reservoir record).

  Motive water; sucked solution (fish nutrients, filtered — filter not specified).

• C6-21Impact sprinkler, arm and spoon. Families I mean: Senninger or Rain Bird. No model — none is selected.

  Water, thrown out. Bearing must not pour.

• C6-22Traveling gun, Nelson Big Gun family (memory of the name). Model not selected. farm reservoir record says "a traveling gun", one gun not two.

  Water at the gun.

• C6-23Three-outlet manifold, Banjo flange stack (C5-22 repeated three times) plus one inlet. Boom has 3 sections. Port size I chose: ¾″.

  Spray mix, one inlet, three section outlets.

• C6-246″ resilient-seat wafer butterfly. Family I mean: Watts-style, series number not re-read. I chose it for the other-site 6″ line (C5-23). No valve is named there.

  Water.

• C6-25Sluice gate: a board lifted in grooves at a flume's end, metering water under it onto a wheel. Peirce Mill's overshot flume, c. 1969 (HABS DC-22 sheet 15: the gate in its frame at the flume's lip, a rod and ring to lift it); the mill gate of Evans 1795, art. 73 ("the gate is drawn about 12 inches behind the perpendicular"). Added 2026-10-17 for Peirce Mill round 2

  Water in an open flume, held back from the wheel; what passes goes UNDER the board, in proportion to its lift. Not C7-17's stop-log, where the water goes over a fixed board

• C7-01Flanged single-hole tank bulkhead; Banjo-style flange, gasket and nut; proposed 300 gal tank application, outlet size/material unstated

  Spray mix at atmospheric head, air outside. I do not put boom ~55 PSI on this tank. The file never says the tank is pressurized.

• C7-02Bolted two-flange liner penetration; Agri Drain-style boot, Firestone pond-flange reference; brand unselected, RPE/HDPE liner context

  Stored water against sand. Seepage is the enemy.

• C7-03Filter-bowl O-ring closure; Banjo-style polypropylene T-strainer, Pentair Pentek bowl reference; boom location speculative

  Spray mix; screen holds solids.

• C7-04Curved-wall saddle seal; Hayward saddle reference

  Water inside

• C7-05Flexible tank grommet; Uniseal reference

  Water inside

• C7-06Cartridge end bypass seal; Pentair cartridge reference

  Dirty water upstream

• C7-07Y-strainer cleanout seal; Banjo Y-strainer reference

  Water inside

• C7-08Removable standpipe socket; Tetra pond-filter reference

  Water inside

• C7-09Demister perimeter/seam seal; shop scrubber finding 23

  Wet air inside

• C7-10Bottom drain plug seat; Valterra drain reference

  Water inside

• C7-11Backpack screw cap and lid gasket. 4 gal tank. Brand of the tank not stated. Failure is in farm backpack record: lid gasket compressed or worn.

  Spray mix inside (glyphosate salt, clopyralid MEA, AMS/surfactant, alkaline cleaner). Air outside.

• C7-12Fill-neck wetting basket, 20- to 35-mesh. The backpack file records the glyphosate label's instruction (label §7.0 in that file). No brand.

  Solids out of the fill. Not a pressure seal. Spray mix is poured through it.

• C7-13TeeJet slotted tip strainer behind the AIXR tip. Mesh for this farm: not stated. I am not picking 50 vs 100.

  Spray mix, last screen before the orifice.

• C7-14AG Spray #83250 diaphragm gauge isolator. Named in farm boom record. Diaphragm section not opened.

  Spray mix on the boom side. Gauge side must stay free of spray. Fill fluid: not stated. Do not call it glycerin — glycerin is the Phase-1 gauge.

• C7-15Suction screen can, Hypro or Banjo line strainer, on the inlet of C6-08. Mesh not stated.

  Spray mix or water; keeps solids out of the pump. Air must not enter.

• C7-16Slide-in forebay screen. No brand. I chose a sliding frame because the file says a sediment forebay "that can be cleaned out" and draws no detail (farm reservoir record).

  Runoff solids vs reservoir water. Not a watertight seal.

• C7-17Raceway stop-log: a board in a slot at the quiescent outlet. I chose the board because the file requires that zone and a place to take solids, and draws no weir. Water depth kept ~2.5–3.5 ft so velocity still cleans (farm reservoir record).

  Water over the board; solids held behind it. This row interrupts solids, not water.
