JINTAI 7900/7925/7950

ASTM F104:f712120-A9B3E22K5L 151M5

Asbetteros-free compression gasket material


JINTAI 7900/7925/7950 is a general-purpose economical compression gasket material plate that can be used in weakly corrosive working conditions of pipelines, equipment and OEM equipment whose media are steam, hydrocarbons and refrigerants. This gasket material is an economical alternative material where the working conditions and uses are not severe:

1. Good sealing performance greatly reduces users’ production costs.

2. The multifunctional gasket has better properties than traditional economical gaskets.

3. Anti-stick properties reduce sealing surface cleaning time

4. Good compressibility and resilience ensure good sealing.​


JINTAI 7900/7925/7950 contains high-strength aramid fiber, and its adhesive is high-quality nitrile rubber (NBR).

Anti-stick properties:

All JINTAl compression gasket materials have gone a long way in developing bonding agents with better anti-stick properties. All JINTAl compression gasket materials successfully pass the MIL-G-24696B 300°F/48 hrs Naval Facility Anti-Adhesion Test.

Note :

The performance of the ASTM standard is measured based on the base frame plate thickness of 1/16 inches, but ASTM F38 is measured based on the plate thickness of 1/32 inches. These properties can only be used as a general reference and cannot be used as a basis for risk or rejection. The data listed in this table are within the normal range of product performance. These data should not be used to compile technical specifications or used alone as a basis for design.

*When used for nominal pressure Class 300 or above, please consult our representative office.
