Q-248 FLUOROELASTOMER 75 Q RING

This quad-ring is supplied in AS568-248 black Viton® (FKM) 75 Shore A supplied with an inside diameter of 4.734 in (120.24 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 5.012 in (127.3 mm), catalogued under part number QV70248. It seats in a standard o-ring gland while offering improved dynamic performance.

Viton® (FKM) is specified here for outstanding high-temperature capability and long service life in hot, chemically aggressive environments. The material holds up against petroleum oils and fuels, aggressive chemicals, and chlorinated solvents. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with low-molecular-weight organic acids or amines. The profile itself contributes two sealing bands per contact face rather than one and lower compressive load required to achieve a seal.

Maintenance and OEM teams specify it across high-temperature process equipment, automotive fuel systems, and semiconductor equipment.

This item is sold individually under part number QV70248. Unit weight is approximately 7.8991 g and nominal inside diameter is listed as 4 3/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
