Products Description
AS568 O-Rings (governed by SAE AS568 Aerospace Standard) are the globally recognized benchmark for imperial fractional size elastomeric sealing rings. Encompassing 369 standard sizes across five distinct cross-section thicknesses—ranging from 1/16" up to 1/4" nominal cross-sections—AS568 O-rings ensure universal interchangeability, dependable static face sealing, and high-pressure dynamic cylinder sealing. We manufacture and stock the full spectrum of AS568 dash numbers (from 001 to 475) in premium NBR (Buna-N), FKM (Viton™), Silicone, EPDM, and high-performance FFKM perfluoroelastomers, engineered to stringent aerospace and automotive quality tolerances.
Product Features
Full AS568 dash size coverage
Fully covers all standard sizes from Dash 001 to 475 across the 5 nominal cross-section series (000, 100, 200, 300, 400), ensuring seamless global interchangeability.
High-precision flash-free molding
Produced using multi-cavity precision tooling with micro-parting lines, preventing parting line defects, spiral failure, and extrusion under high hydraulic pressure.
Comprehensive material compounding
Available in NBR (Buna-N), FKM (Viton™), EPDM, Silicone, and FFKM with hardness options from 60 to 90 Shore A, tailored for oils, fuels, coolants, and steam.
Automated optical sorting inspection
