If in doubt, measure the groove and compare to the 3\/8 in ID and 9\/16 in OD specifications. \u003cbr\u003e\n- Clean the seating grooves and surrounding surfaces to remove debris or old lubricant before installing the new O-ring. \u003cbr\u003e\n- Lightly lubricate with a silicone-based lubricant suitable for rubber to reduce friction during installation and extend ongoing seal life. Avoid petroleum-based lubes, which can degrade rubber over time. \u003cbr\u003e\n- Install the ring evenly in its groove and avoid twisting or pinching.
