## Long description

Rawiplast universal extendable connector B311 is a drain trap adapter designed for connecting sink and basin traps to waste pipes. The connector features a 6/4” inlet and a 40/50 mm outlet, and its telescopic body is adjustable from 350 to 800 mm to accommodate different installation depths and offsets. Constructed for compatibility with standard waste plumbing, this extendable connector helps create a sealed and compact connection between the trap and the horizontal or vertical drain run.
Advantages
The extendable design covers a wide range of distances, reducing the need for additional pipework or couplings. Its dual-diameter outlet accepts both 40 mm and 50 mm waste pipes, making it suitable for varied plumbing systems. The connector provides a straightforward mechanical connection with reliable sealing surfaces to minimise leaks and simplify maintenance. Its compact profile allows fitting in constrained cabinet or wall spaces while maintaining proper drainage alignment.
Suitable for
 Adjusting the distance between a sink or basin trap and the waste pipe
 Retrofitting or replacing existing trap connectors in kitchens and bathrooms
 Connecting traps to horizontal or slightly offset vertical drain runs
 Installations requiring compatibility with both 40 mm and 50 mm waste pipes
Key specifications
 Inlet connection: 6/4” (compatible with standard trap outlets)
 Outlet connection: 40/50 mm dual-diameter
 Adjustable length: 350–800 mm telescopic range
 Material: durable plumbing-grade plastic (non-metallic)
 Profile: compact telescopic design for constrained spaces
How to use
Measure the required distance from the trap outlet to the waste pipe and extend the connector to the appropriate length within the 350–800 mm range. Insert the connector inlet onto the trap outlet and secure according to the trap design (push-fit or with existing fastening). Select the correct outlet diameter section for the waste pipe (40 or 50 mm) and engage the connector onto the waste pipe with a push-fit or compression coupling as applicable. Ensure all sealing surfaces are clean and seated correctly, then test the connection by running water and checking for leaks. Trim the telescopic section only if necessary and follow local plumbing practice for support and alignment.
Usage recommendations
The connector is intended for indoor wastewater systems; avoid use in exposed outdoor locations or with aggressive chemicals. For long horizontal runs or where greater alignment precision is required, provide additional pipe supports and check local plumbing codes for trap venting and slope requirements.
