Square Profile Viton O-Ring Dash 226 Pack of 5

This pack contains five black Viton O-rings with a square cross-section and dash number 226. Each ring has a nominal inside diameter of 2 inches and a nominal width of 1/8 inch. The material is rated for a temperature range from -15 to 400 degrees Fahrenheit and carries FDA approval for applicable uses.

Check groove dimensions

Verify that the sealing groove matches the actual inside diameter of 1.9 inches and actual width of .139 inches for a proper fit. Confirm that the rectangular cross-section suits the gland design and that Viton is chemically compatible with the fluids or gases in the system. The rings are metal detectable but not X-ray detectable, which may affect inspection requirements.

Thermals noise and power draw in normal use

As static sealing components these O-rings generate no noise and draw no power during operation. The Viton material maintains sealing integrity across the rated temperature span of -15 to 400 degrees Fahrenheit with a durometer hardness of 75A. Performance depends on correct installation and the condition of the mating hardware surfaces.

Questions about this item

Does the pack contain five O-rings or do I need to order extras?

The pack includes five square-profile Viton O-rings, dash number 226, so no additional rings are required for a standard five-seal job.

Should I choose the dash 226 size or a different dash number for a 2 inch nominal bore?

Dash 226 matches a nominal inside diameter of 2 inches and an actual inside diameter of 1.9 inches, making it the correct size for that bore.

Will the 75A durometer hold up at the 400 degree upper temperature limit in my hydraulic cylinder?

The 75A durometer Viton material is rated for continuous service from -15 to 400 degrees F, so it will maintain seal integrity at the top of that range.
