For over 100 years we ve never wavered from our first and only mission to make the best piston ring possible.
Hastings piston rings gap.
At hastings we manufacture a bold and broad offering of piston rings one that spans thousands of applications for virtually any engine.
Maximum ring gap is an important part of ring performance in that too much gap results in lost compression power loss and ultimately poor oil control.
The ideal situation sees this gap held to an absolute minimum.
Because piston rings need to be expanded to fit over the diameter of the piston itself before they find their home in the ring grooves they have to be split in some way in order to allow installation.
Hastings offers piston rings for nearly any application worldwide from automotive and truck to agriculture industrial small engine as well as marine and high performance engine applications.
This can directly bleed off the precious cylinder pressure that is so difficult to achieve.
When winding compression rings downward it s a good practice to use a small screwdriver to keep the gapped end of the ring away from the piston.
This prevents the ring gap from scratching the piston.
To find the proper ring end gap multiply your bore size by the ring end gap factor listed on the chart i e street naturally aspirated 4 000 bore x 0065 gap factor 026 total top ring end gap.
It stands to reason that a large gap at the end of the ring makes for an easier leak path.
Setting the correct ring gap on aftermarket piston rings is crucial for proper performance and engine longevity.
Hastings revolutionized oil control ring design with the invention of the hastings flex vent oil control ring and it is now the accepted standard in the industry.
Hastings recommends a minimum of 0035 gap per inch of cylinder diameter.
Hastings offers piston rings for nearly any application worldwide from automotive and truck to agriculture industrial small engine as well as marine and high performance.
With the most comprehensive line of piston rings compression rings and oil rings in the world we have a piston ring for practically any application racing automotive heavy duty transportation agriculture industrial small engine and more.
Your hypereutectic performance piston will expand less than typical cast or forged pistons.
4 bore x 0035 0 14 minimum gap.
Once installed rotate the gaps so they don t coincide.
