About Precision Products

Precision Products Ltd. manufacture and supply piston rings primarily for marine diesel engines. We also offer piston rings and metallic sealing rings for other industrial applications.

With modern marine engines producing so much power and use of contaminated Heavy fuel oils, life in the combustion chamber soon exposes poor quality products! In this modern age of importing cheap products manufactured in China and India, sounds cost effective for consumables, but is false economy against UK produced piston rings.

Control of quality is necessary from start to finish in production and needs experienced personnel. Simple things such as ordering scrap cast iron for melting into casting for the production of piston rings, if left in the wrong hands will cause serve problems.

If the raw material fails, then with best machinery available, it’s impossible to supply rings suitable for use in modern engines. We have invested heavy for the last 8 yrs to bring our factory to the front to supply good quality piston rings at reasonable price, but to Original Engine builder specifications. This is why Precision Products Ltd is now a major supplier to engine builders and licensees worldwide. Please take a look round our web site and then give us a call and lets see if we can be of a assistance.
