About T-seal Rod Shaft Ring
Double Acting T-seal made of HPU-MDI;suitable for heavy duty applications.
This T-seal distinctive cross-section is extremely functional .the elastomeric seal element consists of a flange and a body, each of which has a multuple purpose ,The flange provides the static seal against the bottom of the groove .provides positive radial actuation of the back-up rings,and stabilized the seal against rolling in the grooves,the body providesthe squeeze or interference seal against the dynamic surface,loads the flange to enhance the static seal against the groove, and contributes alastomeric mass to the downstream flange to displace the back-up ring radially .the squeeze effected during installation duplicates that of an O-ring ,giving the T-seal its ability to seal at the lowest pressures ,Finally ,the square or rectangular shape of the T-seal assembly with its back-up ring eliminates the spiral failure mode characteristic of O-rings, T-seal cannot spiral fail.
