Product Description
Complete Piston Seal - Pneumatic - DP Type FESTO Cylinder Piston Ring
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, this integral piston seal prevents excessive lateral loads. It integrates sealing, guiding and buffering functions without requiring extra parts. With excellent wear resistance and strong corrosion resistance due to full rubber covering, it performs reliably in complex operating conditions. The built-in pressure relief groove balances pressure rapidly, enhancing cylinder efficiency and extending equipment lifespan.

Key Features & Benefits
- Double-acting DP-type seal with double sealing lips vulcanized and bonded to a metal skeleton
- Integrates three functions: sealing, guiding, and buffering in a single component
- Optimized geometry and material suitable for oiled or oil-free air (initial pre-lubrication required during installation)
- Buffer channel located on piston end face provides mechanical buffering for the cylinder
- Built-in integrated pressure relief groove enables rapid response under full pressure load
- Excellent wear resistance and strong corrosion resistance with full rubber coverage
- Optimized sealing lip design ensures smooth operation and reduced friction
- No additional sealing elements needed - easily fixed on piston rod
- Integral static sealing function allows for simple installation
- Good media resistance with proper material selection
- Reduced installation height shortens oil cylinder dimensions
- 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.
