About Cometic
Cometic Gasket manufactures multi-layer steel head gaskets and complete gasket kits in Concord, Ohio. On a built V-twin running higher compression or a big-bore kit, the MLS head gasket is what keeps the top end sealed — which is why Cometic is the default spec on so many engine builds.
Keep your Evolution Sportster's oil pump sealed and prevent leaks with this Cometic O-ring 5-pack. These OEM-spec replacements are designed to seal the dipstick at the pump housing, a critical point for maintaining oil integrity.
Why riders pick this
- 5-pack for multiple services or spares
- OEM-spec diameter and thickness
- Direct replacement for stock oil pump O-ring
- Prevents oil seepage at the pump housing
Even small leaks can lead to big problems, and a compromised oil pump seal is one to address quickly. This 5-pack of Cometic oil pump O-rings ensures you have multiple replacements on hand for routine maintenance or unexpected repairs, giving you peace of mind that your Sportster's oil system is properly sealed.

DONT FOLLOW PRINTED INSTRUCTIONS!
DON’T FOLLOW THE INSTRUCTIONS ON THE BOX!!! It says recommended torque is 42 lb/ft. You know what happened at 32lb/ft? One of bolts broke! And I was lucky there was long enough piece sticking out to remove it without drilling out! Check photos.
