Hydraulic Seals

FTL supplies hydraulic seal solutions for light, medium and heavy duty industrial applications. In the case of light and medium duty applications, the application parameters generally allow the use of single element rod, piston and wiper seals.

What is a Hydraulic Seal?

A hydraulic seal is a relatively soft, non-metallic ring, captured in a groove or fixed in a combination of rings, forming a seal assembly, to block or separate fluid in reciprocating motion applications. Hydraulic seals are vital in machinery. Their use is critical in providing a way for fluid power to be converted to linear motion.

Typically these are manufactured from NBR, FKM, PUR and filled PTFE materials and used in conjunction with standard mineral based hydraulic oils. Ensuring that a seal system retains 100% leak free is a primary goal when specifying the seal system.  The tribological qualities of seals vary from one design to another and understating this is key to a reliable system. Seals themselves stay leak free by minimizing friction and wear. This is achieved by a complex combination of material performance and geometric design. 

High pressure high temperature applications often present the harshest environment for hydraulic seals, although equipment operating in ultra-low ambient temperatures can also be equally challenging. With a combination of advanced material technology and innovative seal design, FTL makes both application extremes possible.

Why FTL?

Heavy Duty Hydraulic Seals

Our heavy duty hydraulic seals are manufactured in a choice of NBR, HNBR, FPM and PTFE, to suit the demands of the application.


Piston Seals

FTL engineers will work closely with you to ensure that your piston seals are designed along the same lines as the demands of the application.


Rod Seals

Rod seals work together with wiper seals to protect a hydraulic system against external contaminants, including dirt, dust and outside weather conditions..


Rotary Seals, Shaft Seals and Oil Seals

Rotary Seals involve rotational motion from a shaft and housing. Used in oscillating or rotating parts, their primary function is to keep lubricated fluids in, whilst preventing the ingress of


Wiper Seals

FTL offers a broad selection of wiper seal profiles (either press-in or snap-in), with standard and custom designed solutions available to fit any application.
