Ring Seals & Union Gaskets

Ring Seals

Fittings with a press-fit socket are fitted with a EPDM rubber ring seal as standard.

Depending on the media, this ring seal should be changed to a different rubber material to suit the application.

Union Gaskets

Union fittings are fitted with a (flat) rubber gasket seal and a Gasket (round) ring seal, both EPDM as standard. Depending on the media, both seals should be changed to a different rubber material to suit the application.

Note: Only 316L pipe and fittings are rated to 4000 KPA. This rating is only achieved when using the purpose designed High Pressure jaws and tool.

Leak Before Press Indicator

ConfitPRESS inox press-fit benefits from patented ‘leak-before-press’ O-ring technology which indicates if a joint has not been pressed. The O-ring contains two in-built water pathways that in the unpressed condition allows water to pass through and create a noticeable leak when the system is tested at low pressure (0.1 to 6.0 bar). Any unpressed joints can be pressed without draining down.

Rubber Ring Seals

Fittings are supplied with an EPDM type ring seal as standard in each press-socket.

Depending on the application, the EPDM ring seal may need to be changed to a different type, ie for higher chemical or temperature resistance.

LBP (Leak Before Press)

Features are small depressions that allow un-pressed fittings to drip leak during initial commissioning (testing) to identify joins that require attention.

EPDM Seal: Unpressed seal leaks when tested with water, pressures between 100 to 500kPa.

Note: Some chemical types and/or high concentrations can be unsuitable with stainless steel and ring seals.
