This 45 Degree bend is most commonly at the entrance and exit points of an inspection chamber. The single socket bend comes with one end that is pre-chamfered so that it can be inserted directly into the socket of the main channel of the inspection chamber, thereby creating an access point on the drainage system at a 90 Degree change of direction. This fitting can also be used in conjunction with other fittings such as branches or gullies. The other end is socketed to accept a pipe. If this pipe has been cut to length it should be chamfered and lubricated with our SG100 lubricant prior to insertion into the socket to ensure the best possible seal. Please watch our overview video below
