Description
Parker has combined its proprietary
polyurethane technology with a new
seal design to improve the sealing
performance and assembly of
hydraulic valves. Parker’s Resilon®
4300 polyurethane “D”-rings are a
one-piece, hydraulic valve sealing
solution which delivers longer life over
traditional multi-component seals.
Assembly is easy! The unique “D”-
ring shape provides sealing in critical
areas while reducing the chance of a
seal being cut during installation. This
unique seal design, when combined
with Parker’s proprietary high
performance Resilon polyurethane
extends seal life and reduces warranty
costs.
