  • Viton material withstands -15 to 400 degrees F

Square-profile Viton O-ring pack

This pack contains twenty-five square-profile Viton O-rings in dash number 112. They suit maintenance technicians and engineers who need a fluoroelastomer seal with medium hardness for static or slow-moving applications. The material resists oils, fuels and many chemicals across a broad temperature span. Buyers who need round-profile rings or a different durometer should choose another listing.

Check groove dimensions and media compatibility

Verify that the gland accepts a nominal inside diameter of 1/2 in with an actual inside diameter of .4 in and an actual width of .103 in. The rectangular cross section means the groove width and depth must match the square profile. Confirm the operating temperature stays within -15 to 400 degrees F and that the sealed fluid is compatible with Viton. This product is not X-ray detectable and carries a California Proposition 65 notice.

FDA-approved Viton with metal-detectable additive

The rings are moulded from black Viton rated at 75A durometer and carry FDA approval for food-contact use. A metal-detectable additive helps quality-control systems spot fragments in processing lines. Actual outside diameter measures .693 in, giving a nominal outside diameter of 11/16 in. The square cross section provides a larger sealing contact area than standard round rings in the same groove.

Questions about this item

What comes in the PK25 pack and do I need any extra tools or lubricant to install these Viton O-rings?

The pack contains 25 black Viton O-rings with dash number 112, rectangular cross-section, actual inside diameter .4 in and actual width .103 in; no extra tools or lubricant are included.

Should I choose these dash 112 rings or a different dash size for my application?

Choose dash 112 when the nominal inside diameter required is 1/2 in, nominal width 3/32 in and nominal outside diameter 11/16 in; other dash numbers correspond to different dimensions.

What does the 75A durometer rating mean for sealing performance in a real assembly?

A 75A durometer gives a medium-hard feel that resists extrusion at up to 400 degrees F while still conforming to gland surfaces down to -15 degrees F, and the material is FDA approved.
