1. The nitrile butadiene rubber, which has good abrasive resistance, heating resistance and adhesive strength, is used as material of sealing ring. Reliable tightness.
2. Simple installation. Firstly disassemble the plug, put the sealing ring into body directly facing the sealing groove . Then make the body encase the breakdown and leakage, screw bolt tightly with wrench until water comes out only from the plug outlet. Next quickly put the sealing-trip-wrapped plug onto outlet. No need to stop water during the whole operation.
