The ASTM Standard UPVC Tank Adaptor (Bulkhead Fitting) provides a heavy-duty, leak-proof pass-through connection through the walls of storage tanks, cisterns, barrels, and fluid vessels. Equipped with heavy-duty elastomeric gaskets, it creates a tight mechanical seal capable of withstanding constant hydrostatic liquid pressure.
Technical & Design Advantages:
Dual Elastomeric Gasket System: Premium age-resistant rubber gaskets compress evenly against flat or slightly curved tank surfaces for a 100% watertight seal.
Heavy Coarse Thread Design: Thick exterior threads resist cross-threading and accept heavy nut-tightening torque during installation.
UV & Corrosion Resistant Material: Non-metallic design will not rust, leach chemicals, or degrade when exposed to sunlight or liquid chemicals.
Applications:
Rainwater harvesting tanks and storage barrel outlets.
Agricultural fertigation tanks and pesticide spray vessels.
Industrial water storage and chemical mixing tanks.
Commercial aquaculture and fish tank bulkhead connections.
