The 170℃ & 80Mpa resistant compressing type YS is a special high performance product which is developed and updated by ShangHai JingWeiFeng Industry Co., Ltd lately. It is used for the separately exploitation of oil and gas, testing, mud, acidizing and fracturing seal. This product is made up of high quality rubber based polymer alloy, which conforms to the HG/T 2701、ASTM D412、 ASTM D2240、ASTM D471 standard.
The main advantage of the rubber tube is it can recover with high elastic under high temperature and pressure, which earns a high cost performance comparing to the other same type products. One middle rubber tube matches with a upper and lower rubber tube.

●  Simple structure
●  Convenient for assembling and removing
●  The elastic recover is 100% after unlocking
●  Adapted temperature range: 120℃~170℃
●  Reliable and stable seat locking pressure
●  Houlder protection, good stress dispression
●  Reasonable compressing distance
●  High resistance of locking under high temperature
