Frequently Asked Questions
Do I need pipe lubricant to install the B7051 single socket bend?
Yes, using a dedicated silicone pipe lubricant on the spigot end and the rubber ring seal is strongly recommended. Lubricant allows the pipe to slide smoothly into the socket without dislodging or damaging the seal, ensuring a completely watertight joint.
What is the difference between a single socket bend and a double socket bend?
A single socket bend (like the B7051) has one socket end with a rubber seal and one plain spigot end, allowing it to connect straight into another socketed pipe or fitting. A double socket bend has rubber ring-sealed sockets on both ends to connect two plain-ended pipes together.
The 160mm 67.5° Single Socket Bend (B7051) is an essential underground drainage fitting manufactured by Brett Martin, engineered to redirect effluent and rainwater flows safely around obstacles or corners in main drainage runs. Featuring a intermediate 67.5° angle, this bend offers a gentler turn than a standard 87.5° elbow, helping to maintain high velocity and prevent debris buildup in high-volume systems.
Built with a spigot-and-socket configuration, one end inserts directly into another socketed pipe or fitting, while the socketed end accepts a 160mm plain-ended pipe. The socket is fitted with a captive ring seal that creates a secure, flexible joint capable of handling natural ground expansion and contraction over time.
Designed for long-term subterranean durability, the B7051 is constructed from premium-grade terracotta uPVC, making it ideal for both domestic housing developments and heavy-duty commercial drainage installations.
