138 Viton 75A — 29.82 ±0.30 x 2.62 ±0.08 (AS568A)
Part: 138
Material: Viton (fluoroelastomer)
Hardness: 75 Shore A
Size: 29.82 ±0.30 mm (OD) x 2.62 ±0.08 mm (cross-section) — AS568A series
Key properties:
Excellent resistance to oils, fuels, solvents and many chemicals
High temperature use (roughly -20°C to +200°C; intermittent up to ~+250°C depending on compound)
Good compression set and durability
Low permeability vs general elastomers
Typical uses:
Seals in automotive, aerospace and industrial fluid systems
Fuel and hydraulic seals, high‑temperature static or low‑movement applications
Notes:
AS568A size relates OD and cross‑section; confirm whether your spec uses ID×CS or OD×CS
Ensure correct gland design and squeeze for 75A hardness to avoid extrusion or leaks
Request material, hardness and dimensional certification for critical uses; specify compound, color or special tests if needed
Univergo supplies standard AS568A and custom Viton O‑rings. For bulk orders or datasheets, provide part number, quantity and application details.
