SQ 24.77 X 35.09 X 5.16 EP

• EPM (Ethylene Propylene)
• Standard Service Temperature: -65°F - +300°F

Square rings are similar to O-rings however the cross-section is square instead of round. The square cross-section helps prevent rolling of the seal.

Excellent resistance to petroleum products, low compression set and high temperature resistance. The low temperature capability is somewhat restricted, however, in some cases the low temperature sealing capability may be increased by specific design parameters.

Application:

Automotive Brake Fluids, Water/Hot Water, Steam (to 400°F), Silicone Fluids, Some Acids (Dilute), Ketones, Phosphate Esters such as Skydrol

Not Compatible With: Petroleum Fluids, Diester Lubricants

The hardness of rubber compounds is measured by the Shore A durometer, the higher the durometer, the harder the compound. Softer compounds stretch easier and seal better on rough surfaces. Harder compounds offer greater abrasion resistance and resistance to extrusion.

• 60 Shore A is softer than 70
• 70 Shore A is the standard
• 90 Short A is very stiff
