DESCRIPTION
The TR rod T-seal is designed to retrofit o-rings in no back-up, single back-up and two back-up standard industrial reciprocating glands. The TR seal combines a resilient sealing ring with a hard, split back-up ring on each side of the sealing element. Its compact design provides improved stability and extrusion resistance in dynamic fluid sealing applications.
The nitrile flange or base of the T-seal forms a tight seal in the gland and supports the nylon anti-extrusion back-up rings. When energized, the back-up rings bridge the extrusion gap to protect the rubber sealing element from extrusion and system contamination. The TR rod T-seal eliminates the spiral or twisting failure that can occur when o-rings are used against a dynamic surface.
The TR rod T-seal is directly interchangeable with a standard O-ring, O-ring w/Back-up (1 back-up – Intermediate Base; 2 back-ups – Wide Base) seal grooves.
