Deciding specification

Questions about this item

Will these nitrile rubber O-rings soften or leak if the shower runs hot water all day?

Nitrile rubber resists typical shower temperatures and the 1/16 in thickness maintains a stable seal during extended hot-water use.

Do I need any special tools or lubricants to install these 5/16 in ID O-rings on my Acorn Acme shower?

No special tools are required; a light coating of plumber's silicone grease helps seat the rings without damaging the nitrile material.

Can I use these O-rings to repair an older Acorn Zenith shower valve that has a different groove depth?

They are sized 5/16 in ID by 7/16 in OD by 1/16 in thick and are specified for Acorn Acme, Apex and Zenith showers, so they match the original groove dimensions.
