Not sure on sizing? View information on Inside Diameter vs Outside Diameter

Don’t guess your size— verify before you buy.

Pipe and tubing are measured differently, so the same labeled size may not match. The most reliable way to ensure a proper fit is to confirm your outside diameter (OD).

✔ Secure fit

✔ Fewer installation issues

✔ Less returns and delays

✔ Better protection
