Glass-reinforced nylon composite plumbing fittings. Immune to corrosion, electrolysis and dezincification — no bonding wires, no anodes, no bronze. Below the waterline, a complete assembly is four parts:
| 1 Skin Fittings Domed, recessed & high-speed thru-hulls | 2 Load Bearing Collars ABYC H-27, rated to 500 lb | 3 Ball Valves Manual & compact seacocks | 4 Hose Tails Straight, 90° and 120° |
Add two marine-grade hose clamps per joint. Below the waterline the Load Bearing Collar is not optional — it is what takes the assembly to the ABYC H-27 500 lb standard.
