Frequently Asked Questions

It provides a fluid-tight seal inside pumps and valves to prevent leaks under pressure.

Lightly lubricate the o-ring and position it in its groove before reassembling the pump or valve.

It's best to replace the o-ring if worn, as reuse may compromise the seal and cause leaks.
