| At Hastings, we only manufacture piston rings – and for good reason. We believe that manufacturing the best product requires a singular and constant focus. This keeps us focused on what we do best: delivering ultimate confidence for customers around the globe. Hastings delivers what the world wants in piston rings: precision, performance, and confidence, no matter the engine or application. If it has an internal combustion engine, it will run better and longer with Hastings Piston Rings. |
| Performance—it’s on our minds and in your engine. With Hastings Performance Rings, you can expect better oil control, longer engine life, and confidence—from the moment you start. We know what high-performing engines need to exceed in the most demanding conditions—and we’ve put that understanding into every set we make. Hastings Performance Rings are available in three series, each serving increasing levels of engine performance: |
| Stainless Steel Nitride Racing Rings are the perfect match for high performance applications. The stainless steel top rings are gas nitrided to provide excellent wear and scuff resistance to withstand the demands of high performance applications. The second rings in the series are Napier-faced, high-strength ductile iron. The Napier profile provides outstanding cylinder wall oil film control and reduced oil consumption. Our famous Flex-Vent® oil control ring completes this top-of-the-line series. |
| Hastings Steel Moly (SM prefix) and Steel Chrome (SC prefix) top rings are made of highly durable alloy steel coated with either plasma moly impact-resistant alloy or chrome. The alloy steel material allows for reductions in compression ring cross sectional dimensions (axial height and radial width). Along with reducing the engine’s reciprocating mass, these rings can be fitted to the latest designs of lighter, reduced deck-height pistons with restricted ring belt areas. The top and 2nd rings in the series are offered in increasingly thinner axial heights. With the top barrel faced steel ring, a Torsional Reverse-Twist taper cast iron or Napier-faced ductile iron 2nd groove ring and Hastings Flex-Vent oil ring, the Steel Series is a must for high performance sport compact and late model race engines. |
| Our Premium Ductile Series set offers a balance between performance and cost—making it our best-selling ring set. Top rings are made of high-tensile premium ductile iron, coated with plasma moly impact-resistant alloy. Premium Ductile, made with highly malleable Ductile iron, has the durability to withstand high temperatures and pressures, including abnormal combustion events (i.g., detonation and pre-ignition). The top ring is Torsional Positive-Twist, packaged with our reverse twist, taper-faced cast iron or ductile napier 2nd groove. |

1. Inside Diameter: Inside diameter (ID) of the ring when fitted (installed) to the cylinder bore diameter 2. Outside Diameter: Outside diameter (OD) of the ring when fitted (installed) to the cylinder bore diameter 3. Radial Wall: Ring width in the radial (horizontal) direction, ID to OD dimension 4. Axial Height: Ring width (also referred to as thickness) in the axial (vertical) direction, from top-side to bottom-side of ring Clearances 5. Free Gap: Uncompressed (uninstalled) end gap clearance of the ring 6. End Gap: Gap clearance of the ring when fitted (installed) to the bore diameter 7. Back Clearance: When installed, the distance in the piston groove between the ring ID and the back of the ring-groove of the piston (horizontal measurement) 8. Groove Clearance: When installed, the distance between the ring axial height and the piston’s ring-groove width (vertical measurement) Ring Shapes Torsional: Compression ring with ID bevel; causes twisting action; aids in sealing Barrel Face: The curved face (OD) of a ring that makes contact with the cylinder wall; aids in sealing Taper Face: The angled face of a ring Napier: Hook-shaped design on the lower face of some 2nd compression rings; aids in oil control |
 Ring Terminology Ring Face: Front face (OD) of the ring that makes contact with the cylinder wall Ring Side: The top and bottom (axial) surfaces of the ring Positive Twist: An asymmetrical change (created by an ID bevel on top ID of ring) used in a top ring cross section that causes it to twist in an upward direction; it aids ring sealing Reverse Twist: An asymmetrical change (created by an ID bevel on bottom ID of ring) used in a 2nd ring cross section that causes it to twist downward; it enhances oil scraping properties  |
| Piston rings typically come in sets of three rings, starting with the 1st or top-groove compression ring, followed by the second-groove ring and then the oil ring. Their function is to seal off combustion gases, aid in the heat transfer to the cylinder wall, and both lubricate and scrape down oil from the cylinder wall. The top ring serves to seal off the majority of the combustion gases and dissipate most of the heat. While the second ring helps with both of those functions, they also scrape oil from the cylinder walls toward the oil ring. The oil ring provides most of the oil control, metering oil along the cylinder walls on the up-stroke and scraping oil from the cylinder walls on the down stroke. |
| Function: Top compression rings seal against the cylinder wall to trap combustion gases and increase the combustion pressure and efficiency. They also play a major role in the heat transfer process from the piston to cylinder wall and out through the engine block. Materials: Ductile High-tensile Premium Cast Iron; Silicon Manganese; Alloy Steel; Stainless Steel Coatings: Plasma Molybdenum Alloy “Moly”; Chrome Plated; Gas-Nitride; Manganese Phosphate; Black Oxide |
| Function: Second-groove compression rings seal off combustion gases, aid in the heat transfer to the cylinder wall, and both lubricate and scrape down oil from the cylinder wall toward the oil ring to prevent oil from reaching the combustion chamber, thereby often being called a scraper ring. They also provide a second seal for trapping combustion gases, as well as aiding in heat transfer. Materials: Shell Mold Cast Iron; Ductile Cast Iron Coatings: Phosphate |
| Function: Oil rings distribute and regulate (meter) oil within the cylinder wall and help scrape it back into the crankcase. This is necessary to keep the cylinder wall lubricated with a thin layer of the cooler replacement oil and to lower the friction between the piston and the cylinder thus regulating heat buildup. Materials: 1070 Segmental Steel Rails with 201 Stainless Steel Expander Coatings: Chrome |
| A common practice in racing applications is file fitting piston ring end gaps. Most Hastings Performance Rings are available in file fit (+.005") oversizes. Today’s performance piston designs are moving the top compression ring higher for optimal performance. This creates even higher operating temperatures, therefore requiring a larger top compression ring end gap. Also, improved thermal efficiency of a hypereutectic piston alloy keeps more usable heat in the combustion chamber, with less heat moving down through the piston onto the piston skirt and into the oil. Use the chart below to determine the minimum ring end gap. Multiply bore size x ring end gap factor. Example: For a naturally aspirated street engine using a cast piston with 4.000" bore, the top ring end gap would be 4.000 x .004" = .016". The second ring end gap would be 4.000 x .0045" = .018". The oil rails should always have a minimum end gap of .015". |
| Check bearing clearances the modern, fast, accurate way with Hastings Plastigages. Plastigages are a special extruded plastic thread with accurate controlled “crush” properties. They are extremely handy for checking main and connecting rod bearing clearances, oil pump cover-to-gear clearances, and for many other clearance checks. Each box of Plastigages contains 12 strips in individually calibrated envelopes, usually enough to check 12 engines. Available in four clearance ranges. |
