Engineered Seals

Freudenberg Oil & Gas Technologies offers an industry-leading portfolio of FS Seals, S-Seals and T-Seals. Our seals and material capabilities are field-proven, and tested to rigorous industry standards.

Our high-performance materials ensure reliable solutions for extreme and abrasive operations covering a wide temperature and pressure range.

FS Seals
Ideal for sealing large clearances, particularly those on surface wellhead-to-casing assemblies, the FS Seal design supports reduction in installation time, correct placement in the housing and simple installation.

High-performance FS Seals can retain sealing integrity under severe operating conditions, including:

We offer a complete line of FS Seals designed for API standard casing sizes ranging from 2-7/8” to 30” diameter.

T-Seals
Designed to replace O-Rings, the T-Seal design prevents rolling in the seal groove.

S-Seals
Alternative engineered seal design to using T-Seals or O-Rings. Traditional S-Seals utilize metal spring for supporting sealing of various extrusion gaps.
