The design is also considered to be more stable than an O-ring, as the T-seal shape helps to eliminate rolling or spiraling issues.<\/p>\n

Our T-Seals fit standard O-ring grooves, allowing a direct replacement with no hardware modification required. They are double acting and are suited for both reciprocating and rotary motion equipment, with piston and rod profiles available.<\/p>\n

Our standard T-seals are non-locking designs composed of a nitrile 70A sealing element and two integrated split nylon\/polyamide back-up rings. Viton\u2122 FKM sealing element and PTFE back-up rings are recommended for improved chemical resistance.<\/p>\n

Hi-Tech Seals recommends increasing the sealing element hardness to 90A and\/or upgrading to KasPex\u2122 PEEK<\/a> back-up rings for higher pressure (>5000 PSI) handling ability.<\/p>\n

With proper seal design, material selection, and gland tolerances, our T-Seals are proven to handle well over 10,000 PSI. Please refer to the following T-seal Case Study<\/a>.<\/p>\n
