Name: China Customized Pneumatic Piston Seal Manufacturers Suppliers Factory - Good Price - DEDE Seal
Brand: DEDE Seal
SKU: 314659809

DEDE Seal Co., Ltd. is one of the most reliable manufacturers and suppliers of pneumatic piston seal in China. If you're going to buy bulk pneumatic piston seal made in China, welcome to get pricelist from our factory. All customized seals are with high quality and competitive price.

Pneumatic Piston Seal is embedded on the piston inside air cylinders, acting as an isolation partition for two pressure chambers. It effectively stops compressed air from flowing across both sides of the piston, enabling full power transfer and steady, glitch-free reciprocating strokes. DEDE adopts premium NBR compound to produce piston seals, delivering consistent sealing performance and extended service life for all kinds of industrial automation pneumatic circuits.

FAQ

Q1: What is the difference between piston seal and rod seal?

A: They differ completely in installation position and function and are non-interchangeable. The piston seal is a built-in internal component for bidirectional air isolation and power support. The rod seal is an external component for dust prevention and external air leakage resistance. The piston seal determines cylinder power performance, while the rod seal determines cylinder protection life.

Q2: Why is Pneumatic Piston Seal durable under high-frequency reciprocating conditions?

A: The Seal is made of anti-extrusion and fatigue-resistant polymer material, specially optimized for frequent internal pressure impact and reciprocating extrusion. It resists compression deformation and structural relaxation after hundreds of millions of cycles, maintaining stable sealing performance for long-term automated operation.

Q3: What are the advantages of oil-free type Pneumatic Piston Seal?

A: The Seal features low friction and self-lubricating performance without oil residue or dust accumulation. It operates stably without lubrication assistance, perfectly adapting to dry and clean pneumatic systems in dust-free, food, electronic and pharmaceutical industries.
