PTFE Rod & Piston seals; Double Acting

PTFE rod & piston seals have properties that exceed most other known materials when it comes to friction and stick-slip, which is non-existing when PTFE Seals are used. 
The chemical and thermal resistance of the PTFE Seals are beyond the specifications of most other materials as well.
PTFE Seals are hard and non-elastic and are better suited for compact applications than most other known seal types.
The most important thing for the PTFE Piston Seal as well as the PTFE Rod Seal is to maintain a high level of sealing performance through service life.
The choice of type of piston seal is decided by the function of the cylinder, but the overall demands for the PTFE seals can still differ in many respects.

Double acting

For double acting cylinders, it is vital to use double-acting seals as well, instead of two single-acting seals that can easily cause a breakdown.
The double acting PTFE Seal is designed to operate with pressure from either side and should fulfil as great a demand for absolute tightness at resting position as the single acting PTFE seal.
The PTFE Seals which Accofluor A/S supply, either standard or custom designed, exceed the highest known standards to PTFE (Teflon*) Seals today. Our key elements are quick response and short delivery times alongside our good customer service.
