Re: NIKON WP-N3 HOUSING O-RING

What I do when replacing an O-ring unavailable from the equipment supplier is to measure the ring cross-section diameter and its major diameter then visit O-ring supplier sites and get a match. Look for a low durometer material. It’s an easy process, but you may need to borrow dial calipers. O-rings come in only a few cross-sections. Silicone is a good material.

The easiest way way to measure major diameter is to measure total length and divide by pi.

show the dimensions here and I can help find a seller.
