Description
DP Integral Piston Seal Ring | All-in-One High-Pressure Hydraulic Sealing Solution

Wear & Oil Resistant | Shockproof & Pressure-Reducing | Premium Quality

Product Overview

Suitable for cylinders with end buffers, it prevents excessive lateral loads. Integrating sealing, guiding and buffering (no extra parts needed), it has good wear resistance and strong corrosion resistance (full rubber covering) for complex conditions. With a built-in pressure relief groove, it balances pressure fast, boosting cylinder efficiency and prolonging equipment life.

Key Features & Benefits
  • The double-acting DP-type seal is an integral piston seal with double sealing lips, vulcanized and bonded to a metal skeleton. It integrates three functions: sealing, guiding and buffering.
  • Optimized in geometry and material, it is suitable for oiled or oil-free air (initial pre-lubrication required during installation). The buffer channel is located on the piston end face, and its integrated design provides mechanical buffering for the cylinder.
  • Featuring a built-in integrated pressure relief groove, it enables rapid response (under full pressure load). It has excellent wear resistance and strong corrosion resistance due to full rubber coverage. The optimized design of the sealing lip ensures smooth operation.
  • No additional sealing elements are needed, and it can be easily fixed on the piston rod. Its integral static sealing function allows for easy installation. With the right material selected, it offers good media resistance. The integral piston structure reduces the installation height, thereby shortening the oil cylinder.
  • This integral piston is suitable for almost all types of cylinder designs.
Applications
  • Heavy Machinery: Hydraulic cylinders for excavators, cranes, and bulldozers.
  • Industrial Presses: Injection molding machines, stamping presses.
  • Energy Sector: Hydraulic systems in wind turbines, oil drilling equipment.
  • Marine & Offshore: High-pressure hydraulic actuators.
  • Mining Equipment: Hydraulic roof supports, drilling rigs.

Case Study: A construction equipment OEM reported a 40% reduction in assembly time and zero field failures after switching to DP Integral Seals.
