Brett Martin 45° Double Socket Twinwall Bend with Seal

Brett Martin 45° double-socket bend for twinwall drainage pipe systems — a pre-formed angled fitting that lets you change the direction of a drainage run by 45°. It is designed to be used with twinwall surface‑water drainage pipes.

Brett Martin 90° Twinwall Tripple Socket Branch

This is a 90° Triple-Socket Branch (T-junction / T-branch) designed for twinwall drainage/ surface water systems. “Triple socket” means it has three socket-ends — one for the incoming (main) pipe and two for branching or continuation — allowing three pipes of equal diameter to meet or split at a 90° angle.

Brett Martin 45° triple socket Branch Twinwall with Seals

This is a 45° twinwall junction / branch fitting from Brett Martin, designed for use in surface‑water / land‑drainage systems using twinwall drainage pipe. It’s part of Brett Martin’s “Twinwall Multi‑Fittings” range, which covers nominal pipe diameters of 150 mm, 225 mm and 300 mm. The junction comes with seals included — no need to order sealing rings separately (for the nominal sizes covered).

Brett Martin 225mm 30 Degree Socket Twinwall Bend

This is a double-socket bend for 225 mm internal (≈ 268 mm external) twinwall drainage pipe. The bend provides a 30-degree angle, useful for changing the direction of drainage runs where a modest offset is needed. It is part of the Brett Martin's twinwall drainage system — made from polyethylene (PE), giving a lightweight, robust and corrosion-resistant fitting suitable for surface water, storm water, land drainage, and other similar drainage applications (e.g. highway, agricultural, rail, airport, culverts). The internal twinwall structure (ribbed body) provides high rigidity and resistance to deformation, helping the fitting maintain its shape under load and giving long-term durability. The double-socket design allows it to connect easily with compatible twinwall pipes, ensuring consistent internal socket diameter and easier assembly.  The product is compatible with other BBA-approved twinwall pipes and fittings (as per the manufacturer’s compatibility lists), which helps if mixing components from different but compliant suppliers. For watertight joining, sealing rings (typically two per bend) are required. Some suppliers include these with the bend, but it’s worth checking on your order to ensure the seal is included.

Brett Martin 90° Socket Twinwall Bend

The 90° bend lets you change direction in drainage pipe runs, commonly used in surface water or stormwater drainage systems for domestic, agricultural, or civil-engineering drainage. Because it’s compatible with other BBA-certified twinwall pipes/fittings, it integrates into broader drainage networks (e.g. land drains, soakaways, soakaway-crate systems, French drains, etc.) Sies and standards The twinwall fittings from this range cover nominal pipe diameters from 150 mm up to 300 mm (and larger for bigger systems) depending on application. The 90° double socket bends (like TB90) are listed among the standard fittings in the manufacturer’s product guide. Seals for twinwall fittings conform to recognised standards (e.g., rubber ring seals to BS EN 681‑1).

Brett Martin 225mm x 150mm 90 Degree Twinwall Branch

This is a 90° twinwall branch junction (also described as a “triple socket branch”) from Brett Martin, with a 225 mm main pipe connection and a 150 mm branch. It is designed for use in surface water drainage, stormwater drainage, and general land drainage systems — such as highway drainage, agricultural drainage, rail/airport drainage, or landfill drainage. You’d use this junction when you have a main 225 mm twinwall drainage line (e.g. carrying surface water runoff) and need to branch off a 150 mm line — for example to redirect some flow to a different drainage run, to divert water to a soakaway, or connect to another drainage utility. The 90° angle is useful where the branch must go off at a right angle from the main run.

Brett Martin 45° Junction Twinwall Branch with Seals

This is a 45° junction (also sometimes called a “Y-junction”) designed for use in underground drainage / surface-water management systems. It is a twinwall-style junction, meaning it’s designed to connect with twinwall drainage pipe (corrugated or twin-walled pipe) rather than traditional solid-wall sewer pipe. It comes with integral or supplied seals (rubber sealing rings), so that pipes inserted into its sockets form a watertight connection without needing additional sealing components.

Brett Martin 300mm 90 Degree Bend Twinwall

Nominal diameter: 300 mm Twinwall pipe system. Fitting type: 90° bend (double‐socket) — designed to change direction by 90° in a Twinwall drainage run.
