.275" C/S (1/4" NOMINAL)

This o-ring cord stock is supplied in black Aflas (TFE/P) 75 Shore A with a cross section of 0.275 in (6.99 mm), catalogued under part number 0281275. It lets you fabricate a custom-size seal on site by cutting and splicing to the required circumference.

The material holds up against high-temperature steam, amines and corrosion inhibitors, and sour gas and hydrogen sulfide. Aflas (TFE/P) is widely chosen for exceptional resistance to amine-based additives and high-temperature steam capability that most fluoroelastomers cannot match. It is not the right choice where aromatic hydrocarbons or low-temperature dynamic service are present.

Typical settings include chemical processing, power generation, and downhole tooling.

This item is sold by the foot under part number 0281275. Application requirements vary, so validate compatibility with your process conditions prior to installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
