Technical notes
The 144-5695 is the intermediate (second) compression piston ring used on Caterpillar 3500-series engines, including the 3508, 3512 and 3516 families and the 3512B marine configuration. It seats in the second ring groove of the piston, below the top compression ring, and works with the top ring (214-6066) and a further ring (223-6361) to seal combustion pressure and manage blow-by and oil control across the 170 mm bore. Because it is a single ring within a per-cylinder set, order quantity must match cylinder count and ring position — confirm the engine arrangement/serial number before ordering, since groove and ring profiles differ between the 3508, 3512 and 3516 builds. Distributors list both genuine Caterpillar and new-aftermarket replacements; no published supersession was found in the sources reviewed.
Compliance
Material certification and OEM traceability documentation available on request for genuine Caterpillar units; aftermarket equivalents are sold as non-OEM replacements.

Frequently asked questions
- Does 144-5695 fit the Caterpillar 3512B marine engine?
- Yes. It is cataloged for the 3508/3512/3516 family, which includes the 3512B. Always confirm against your engine arrangement/serial number, as ring profiles vary between the 3508, 3512 and 3516 builds.
- Is 144-5695 a complete ring set or a single ring?
- It is a single ring — the intermediate/second compression ring. A complete per-cylinder rebuild also uses the top ring (214-6066) and additional ring 223-6361, so order quantities by cylinder count and ring position.
- Are aftermarket versions of 144-5695 available?
- Yes. Distributors offer both genuine Caterpillar and new-aftermarket replacement rings; aftermarket units are sold as non-OEM equivalents, typically at lower cost with their own warranty terms.
