EPC 100 - Piston Coating
EPC 100 is similar to hard anodizing. The .002 dimensional change, increases piston life and H.P. by evenly controlling part expansion while reducing friction and part temperature. This coating can be applied to new or used pistons. When being applied on new pistons, we recommend that pistons are machined to allow for the added dimensional change in the ring grooves. But if this is not desired we can mask the parts to maintain the current dimensions.

EPC 100MI - Coating features a textured crown and all the benefits of EPC 100. The texturing that is produced on the crown helps to distribute the impact of the combustion cycle. This texturing also helps in atomizing the fuel for a more even fuel burn.

EPC 100RG - This coating eliminates ring welding and ring groove wear. This coating changes groove tolerances, manufacturers must allow clearance. When applied tighter ring tolerances can be achieved thus allowing for greater horse power.

EPC 102 - This coating is the combination of our EPC 100T and our EPC 108 Crown Coating. This coating reflects heat into the combustion chamber and will withstand 2100 degrees promoting even thermal expansion, increasing part life and exhaust gas scavenging.

EPC 103 - Aerospace quality hard anodize. EPC 103 is the same coating you see on Top Fuel pistons. It is used to reduce friction under extreme conditions and excessive wear from high rod angles. Hard anodized pistons will withstand greater temperatures than uncoated pistons. This coating cannot flake, chip or peal.

EPC 104 - This coating is the combination of our EPC 107 and our EPC 108 Crown Coating. This coating reflects heat into the combustion chamber and will withstand 2100 degrees promoting even thermal expansion, increasing part life and exhaust gas scavenging.

EPC 107 - Piston Skirt Coating
Our lubricating Piston Skirt Coating reduces friction, as well as inhibiting galling and seizing while adding minimal dimensional change. This coating is applied to the skirt area only. The typical dimensional change is .0003 to .0005.

EPC 109 - Piston Skirt Saver
The “Skirt Saver” coating is designed to be applied to already used pistons. This coating allows for a larger dimensional build up correcting surface imperfections. The typical dimensional change is .0005 to .001.
