PSC PISTON SEAL ASSEMBLIES

$5.15 – $176.73

The Style PSC is a double acting piston seal designed to replace o-rings, quad-rings, and T-seals with the same groove dimensions (O-ring dash number). Style 575 urethane back-up rings may be added to either or both sides of the 'PSC' to accommodate wider groove widths. The PSC is made of 95A Durometer polyurethane, giving it high extrusion and abrasion resistance. The crowned sealing surface produces a positive seal from vacuum to high pressure.

NOTE: Piston diameter 'I' dimensions are given for pistons without wear rings.

PSU PISTON SEAL ASSEMBLIES

$5.36 – $44.71

Our Style PSU piston seal, or uniring, is a laminated one piece double acting seal made of cast polyurethane. The tough outer layer is highly resistant to abrasion and is impregnated with molybdenum disulfide to reduce friction. The softer inner layer acts as a static seal and also energizes the OD to make full contact with the bore. This seal may be used to replace an existing Uniring or other seals of the same dimensions - O-rings, O-rings with back-ups, T-seals, U-seals, etc. NOTE: Piston diameter 'I' dimensions are given for pistons without wear rings.

SPR PISTON RINGS

$8.11 – $209.61

IRON PISTON RINGS
When using iron piston rings, it is crucial to use the correct groove design for proper performance of the cylinder. Please use the following guidelines when cutting an iron piston ring groove

GROOVE WIDTH:: To permit the ring to slide freely into the groove, the groove must be at least 0.001 in. wider than the maximum piston ring width with a tolerance of +0.003 in./-0.000 in.
GROOVE DEPTH:: Grooves must be at least 0.015 in. deeper than the maximum radial wall thickness of the piston ring with a tolerance of +0.003 in./-0.000 in. This is to avoid any possibility of the ring bottoming in the groove when the ring is compressed to its working diameter.
RADIAL CLEARANCE:: The radial clearance between the cylinder bore and piston should be less than 1/3 of the radial wall thickness of the piston ring to ensure sealing effectiveness.
