Thru-Bulkhead Threaded Tube

Threaded tubes to pass plumbing or wiring through the bulkhead of your boat


Thru-Bulkhead Threaded Tube

TruDesign Thru-Bulkhead Threaded Tubes are moulded from a glass-reinforced nylon composite. High strength, high-modulus glass fibres within the nylon composite provides dramatic strength, stiffness, toughness, and dimensional stability.
TruDesign fittings eliminate the corrosion and electrical bonding problems associated with metallic fittings.

Designed to be used in conjunction with our range of threaded female fittings, the Threaded Tubes provide a simple and tidy solution for passing plumbing through the bulkhead of your boat.
