Designed for use on 76mm, 102mm and 152mm diameter pipes this unit can be installed in either vertical or horizontal pipework. When installed it is important to ensure that the spigot end is on the out ow end of
the fitting. The unit must be anchored with a metal clamp which should be located on top of the moulded locators, moulded round the body of the stress relief unit, which then allows the pipe inserted into the collar to expand and contract. Note: The body of the SRU incorporates an ‘0’ ring seal.
