Parker provides the most complete selection of dynamic seals for fluid power with our extensive rod, piston, wiper, wear ring/bearing, backups, o-rings and head seals and all-in-one integrated pistons.
Parker’s combination of advanced seal
design technology and material expertise has produced a reliable Zero Leak Rod
Sealing system for hydraulic cylinders for greater equipment output which maximizes
equipment uptime by extending maintenance intervals.Our rod seal packages are
specifically engineered combinations which include material characteristics of
Resilon® polyurethane, a primary rod seal, buffer seal, wiper and wear ring
profile.Each profile’s engineered
geometry has features complementary to the package as a whole – collectively
producing highly effective sealing.
Parker’s tight tolerance wear rings in our 4778 material offer an internally lubricated surface, industry leading tolerances and best-in-class compressive modulus to resist side loading and prevent leakage and damage due to metal-to-metal contact.
The “intelligent” HL rod seal improves the
energy efficiency of hydraulic systems by combining a special functional
principle and a friction-optimized material to ensure optimum friction, as well
as sliding and sealing performance in all pressure conditions. The benefits:
lower energy consumption and seal wear, reduced downtimes, and increased
The HS static radial seal exhibits a number
of strengths versus the existing industry standard – the combination of an
O-ring and back-up ring – for static sealing at high pressures. Simplified assembly, higher sealing effect in
pulsating pressure conditions and longer service life.
The AV wiper provides effective protection
against system contamination and corrosion and thus contributes to the high
availability of mobile machinery. It protects the entire hydraulic system
against dust, dirt, moisture and other environmental influences.
