v型橡胶夹布密封圈-James walker Chevron seals
This robust packing set comprises a gland ring/female adapter, header/male adapter, and one or more intermediate V-shaped rings. The rings are tapered to give an initial interference fit when confined in the seal housing. The resulting radial force together with the fine finish of the lip, ensure a good seal at low or slack pressures. A scarf abutment is used when the seal is needed in split form.
Standard materials are suitable for use with most mineral-based hydraulic fluids, and most fire-resistant fluids of the water/ oil or water/glycol types at up to 100°C (212°F). Also resistant to air, water and most lubricating oils and greases.
