The UNP type xipuli (hole-use) seal is interchangeable and universally compatible with the Hualka UNP groove.

Main advantages: 

◆ Large cross-section and high pressure design 

◆ Excellent water resistance and durability 

◆ Improvements to prevent damage caused by back pressure 

◆ Improvements to prevent creeping 

◆ Utilizes materials with excellent low-temperature resistance 

Application range: Working pressure: ≤40Mpa Working temperature: -30~+100℃ Surface speed: ≤0.5m/s Hardness: 92A±2 Primarily used for piston seals on hydraulic cylinders in walking machinery, outdoor machinery, etc.

Installation: These seals should have axial clearance. To avoid damage to the sealing lip, do not pull the seal over sharp edges during installation. Material: XA-2091 is a nano-modified high-performance polyurethane material independently developed by Xipuli, which has excellent resistance to high and low temperatures and hydrolysis aging, and exhibits minimal compression deformation.
