| Body Material | Solid brass or bronze impact sprinkler head; stainless steel spring / spindle / pivot pin |
| Inlet | 1/2″–14 NPT male (MNPT) |
| Nozzle | Removable straight-bore nozzle, 5/32″ or 4 mm, 24 UNF thread |
| Sealing | NPT thread length provides full seal with thread sealant / PTFE tape only — no O-rings, no gaskets |
| No Polymer Parts | All functional metal parts (sleeve / bearing surfaces other than non-critical washers / bushings excluded) |
| Part 2 — 45° Elbow (Cast Aluminum 356-T6, ASTM B26) |
| Material | Cast aluminum 356-T6 per ASTM B26 |
| Overall Length | ≤ 4.0″ (~101.6 mm); elbow leg ≤ 2.0″ |
| Inlet / Outlet | 1/2″ NPT male inlet · 1/2″ NPT female outlet |
| Stake Interface | Back face (opposite the inlet) locks into a 1″×1″ 90° steel stake via V-clamp + pressure plate, no slippage in service |
| Self-Supporting | Elbow body stands on its own at the top of the steel stake |
| Hydrostatic Test | 600 psig — no leak, no permanent deformation, no structural failure |
| Part 3 — Brass Reducing Swivel (3/4″ FHT × 1/2″ FNPT) |
| Material | Brass reducing swivel with 3/4″ rubber garden-hose washer included |
| Threads | 3/4″ Female Hose Thread (FHT) × 1/2″ Female NPT (FNPT) |
| Operating Performance |
| Working Pressure | 30–50 psi (± 5 psi) |
| Rated Flow | 3.0–5.5 GPM (± 0.5 GPM) |
| Part-Circle Arc | 20°–340° (± 10°) |
| Full-Circle Mode | 360° — achieved by flipping the trip arm out of the stream |
| Spray Radius | 30–45 ft (~9.1–13.7 m) · ± 5 ft |
| Trajectory | 25° (± 3°) |
| Ground Stake with Clamp (matched accessory) |
| Stake Body | 1018 carbon steel angle, 1″ × 1″ × 1/8″ wall × 18″ long, stamped (laser-cut + bent per amendment A0001 also accepted) |
| Point | 21° tapered tip, 2″ taper length, sides reduce from 1″ straight to 0.31″ tip |
| Stake Holes | Five 3/16″ holes starting 4″ from the tip, alternating offset pattern, 1″ center-to-center |
| Stake Finish | Safety orange (T009-OG01) powder coat, 2–4 mil DFT |
| Clamp Plate | 6061 aluminum, 5/8″ × 2-1/2″ × 1/8″, two 1/4″ holes at 1-7/8″ center |
| V-Bolt | 1/4″-20 × 1-5/8″ BL × 2-1/2″ LL × 1-1/2″ tangent, 90° V-bend, 1018 zinc-plated, no powder coat |
| Wing Nuts | 2 pcs per set, 1/4″-20 mild steel, no powder coat |
| Bundling | Stakes bundled 4 per stack, flush at both ends, V-bolt kit at each end; 18″ (±1″) × 10″ × 4″ double-wall carton |
| Workmanship | Best commercial practice; cast parts free of porosity, inclusions, shrink, cracks; metal symmetry within 0.030″ concentricity |
| Typical Use | DIY structure-side wildfire sprinkler set, prescribed-burn perimeter wetting, garden / landscape watering |
| Certification | No third-party product certification required for retail sale |
