Description
The knuckle bend is used to create a compact 90 degree change of direction in 40mm solvent weld waste pipe systems. It is a practical fitting for sink, bath, shower, utility and general plumbing installations where pipework needs to turn sharply in a restricted space.
This 40mm solvent weld knuckle bend is suitable for compatible solvent weld waste systems and is available in Black, Olive Grey and White to match common pipework colours. When installed with the correct solvent cement and pipe preparation, it creates a permanent solvent weld joint.

Using a 40mm Knuckle Bend
Before fitting, check that the pipe and fitting are the correct size, clean and dry. Cut the pipe square, remove burrs, chamfer the pipe end where required and follow the correct solvent weld process for the system being installed.
Once solvent cement is applied and the joint is made, leave the connection to cure according to the solvent cement instructions before testing or putting the waste system into use.
Knuckle for 40mm Waste Pipe Runs
This knuckle bend is suitable for 40mm waste pipework where a sharp turn is needed. It can help route pipework around units, walls, boxing and other restricted plumbing areas.
Before ordering, check the pipe size, colour and bend style required for the installation. If a smoother directional change is preferred, a 40mm swept bend may be more suitable.
