Intended for use with fittings which do not have a Safe gasket. The cover is retained by spring clips which press against the inside of the fitting. It is released by pulling it straight out, and installed by pressing it in. There are one or two handles to help.
The gasket is made from EPDM rubber.
Dp in the table specifies the maximum positive pressure the cleaning cover can withstand without coming loose, when installed from below.
Can manage up to tightness class C.
The corresponding Safe component (of different design) is designated KCU and only fits inside Safe components. Please refer to page KCU.
