氢化丁腈橡胶密封圈-HNBR quad ring
The walle sealing HNBR quad ring offers the following benefits:
1.With HNBR quad ring,the requisite diametrical compression is less than that for o-rings,that reducing friction and hence,wear during dynamic applications.
2.The HNBR quad ring give increased sealing efficiency and,at the same time,provide a lubrication groove,which is an added benefit for dynamic sealing applications.
3.The most important benefit offered by the HNBR quad ring is its superior stability during dynamic applications(especially with reciprocating seals),where,in specific applications,o-rings roll and twist in the grooves(resulting in accelerated ageing).the HNBR quad ring will only slide,which does mot affect its sealing performance.
HNBR quad ring Available materials: NBR, SI, HNBR, SBR, CR, BR, IIR, FPM, FLS NR, IR, PU, EPDM etc.
Applications: Automotive, air conditioner, machinery, Computers pumps, valves, furniture, toys, pneumatic components.
Range of application:
