Can low oil damage piston rings?
Poor lubrication can cause modern piston rings to overheat and lose their tension. When combined with excessive varnish, the piston rings can stick in a collapsed position. Excessive compression ring blowby will force engine oil into the intake air ducting or intake manifold.
Are there any issues with an oil ring?
Issues with oil rings are found in many scholarly works (Baudry and Tichvinsky, 1937; also Refs. 1 through 3. On a website post in September 2012, the Malaysian Government’s OSHA agency alerted readers to catastrophic failures brought on by oil rings ( www.dosh.gov.my ).
What kind of O-rings do oil and gas companies use?
AED (Anti Explosive decompression) materials in FFKM (Markez®), FKM (like Viton ®), Aflas® and HNBR 90 durometer Explosive Decompression Resistant HNBR, tested to NorsokM-710. General purpose Aflas®, steam, sours gas and acid resistant. 90 Durometer Aflas for explosive Decompression applications tested to Norsok M-710.
What should the concentricity of an oil ring be?
Work described by Wilcock and Booser, in 1957, recommends oil ring concentricity within 0.002 inches (0.05 mm). However, in 2009, shop measurements were performed by the author at a pump user’s site in Texas. The oil rings measured in 2009 exceeded the 0.002-inch (0.05 mm) allowable out-of-roundness tolerances by a factor of 30.
When was the shortcomings of oil rings known?
The shortcomings of oil rings were known in the 1970’s, when a then well-known pump manufacturer claimed superior-to-the-competition products.

Why do I need a ring seal on my engine?
If the gap between these components gets too large, you can have several problems: Increased oil consumption: A small amount of oil is needed to lubricate your pistons, but with wear, more and more oil can get past your piston rings and into the combustion chamber. This oil gets burnt off, reducing the amount of oil available for lubrication.
Which is the best O ring for oil and gas?
Marco has developed an extensive line of Markez Perfluoroelastomers dedicated to our Oilfield and Gas customers. Markez is similar to Kalrez® and Chemraz® at significant cost savings and custom O-ring sizes are supplied without additional tooling or setup charges.
