The Brett Martin B4051 is a premium, trade-trusted 110mm double socket 22.5° bend, specifically engineered for subtle directional routing in underground drainage networks.Ideal for both domestic housing and commercial civils projects, it enables smooth rainwater, foul water, and sewage transitions with minimal flow disruption.

What sets Brett Martin underground fittings apart is their high-performance captive lip seal system.Unlike cheaper generic fittings where seals can dislodge or twist out of place when pushing pipes in, the B4051's seal stays completely locked in its groove. This ensures a tight, permanent, and maintenance-free joint that easily absorbs minor soil movement.Built from lightweight but incredibly rugged terracotta uPVC, it’s fast to assemble, easy to handle on-site, and built to last generations.
