Silicone Flange Caps

This cap is an alternative to our Round Silicone Caps when masking off threaded studs or protrusions. These caps are molded with an air vent, which acts as a relief valve for applications where internal pressure is a problem. They also feature an over-sized head and a unique internal gripping design, which makes application and removal easy. Will withstand 315 Celsius 600 Fahrenheit. Also available in EPDM
