Product Description

DAS / KDAS Polyurethane Piston Seal with Silicone Rubber Washers for Machine Tools

High-Performance Piston Seals for Industrial Applications

KDAS polyurethane piston seal and DAS polyurethane piston seal provide superior air sealing performance for demanding industrial environments.

What is a Piston Seal?

Piston seals (also called piston packings) are mounted on piston heads that move through hydraulic or pneumatic cylinder tubes. These critical components feature:

Static housing/groove mounting on the piston head
Single-acting (pressure from one side) or double-acting (pressure from both sides) configurations
Often used in sealing systems with integrated or separate bearings
Back-to-back mounting capability for double-acting arrangements

KDAS/DAS PU Piston Seal Specifications

Item Name	KDAS/DAS PU Piston Seal
Function	Contains pressure on one piston side without leakage to maximize piston movement efficiency. Design considerations include pressure requirements, acceptable friction losses, double-acting capability needs, and piston head configuration.
Export Markets	Taiwan, Europe, America, Asia, Africa, Middle East
Production Equipment	Vacuum vulcanizing machines, large-scale flat vacuum vulcanizers, rubber machines, CNC machine tools, temperature-controlled ovens, and detectors
Material Properties	PU material offers exceptional mechanical strength, abrasion/wear resistance, extrusion resistance, high pressure load capacity, tear resistance, and elongation at break. Excellent flexibility with superior aging and ozone resistance.
Applications	Mobile hydraulics, injection molding machines, machine tools, piston accumulators, and standard cylinder equipment design
