Fluid Power Seals and Tapes

Mask Seals’ Slipper seal consists of an elastomer ring, usually composed of an or, which ensures the persistence of elastic energy necessary to ensure the seal is activated over time, and a segment in filled PTFE, which performs the dynamic action of the seal. As part of the Slipper sealing concept, advanced formulations of PTFE

replace rubber in dynamic zones due to their low friction characteristics and resistance to wear and extrusion.

 

Since it has superior performance, Slipper seals are sought after in modern designs due to its small and simple seat possibilities, which meet the primary need for affordability.

 

Mask Seals’ Fluor/S calibrated tapes are designed to self-lubricate bearings for pistons and rods by avoiding metal-to-metal contact and reducing friction coefficients and wear by using specific formulations of filled PTFE. Mask Seals standard and customer requirements are used to supply these tapes in continuous length rolls.

 

For customers manufacturing Slipper seals and finished parts in their workshops, Mask Seals provides premium grade PTFE tubes.

a. Semi-Finished Products

Mask Seals offers its customers round bars and sleeves in pure and filled PTFE, Maskseal-1000, HPP – High Performance Polymers – such as PEEK, PCTFE and others on specific request, all guaranteed to meet the same quality level as the raw materials used for the finished products manufactured in-house.

 

With the multiple tools available at Mask Seals, nominal diameters are optimized so that dimensions are as close to the final product dimensions as possible, reducing swarf, machining times, and associated costs, as well as guaranteeing the highest quality raw materials.

 

 

 

 

b. Slipper Rings and Fluor/S Tapes

PTFE filled segments form the dynamic part of the Slipper gasket, while an elastomer ring, usually an O-ring, guarantees the fit of the seal for a long time by ensuring a constant elastic energy. In Slipper rings, advanced PTFE

formulations replace traditional rubber in the dynamic areas due to their low friction and resistance to wear and extrusion.

As a result, sealing is subjected to considerably higher technical limits. Thanks to its very small dimensions and ease of installation, the Slipper gasket is an excellent choice in modern projects where primary needs are met, as well as its high performance level.

By avoiding kinetic metal-to-metal contact, Mask Seals’ Fluor/S calibrated tapes in filled PTFE have been successfully used to produce self-lubricating piston and rod bearing rings, which reduce wear to a minimum. In accordance with customer needs and Mask Seals’ standards, tapes can be supplied with teardrops or diamonds ‘oil pockets’, as well as chamfers (broken edges). These are supplied in continuous length rolls as per customer’s requirements.
