SPK-TS is a four piece double acting heavy duty piston seal which consists of one TPE profile ring , one elastomeric nitrile rubber to preload sealing element and two thermoplastic back-up rings.
PRODUCT ADVANTAGES
- Simple groove design
- Superior performance in high and variable pressure
- Long service life
- Very good sealing performance at shock pressures
- High resistance to abrasion
- Ultimate resistance in water based fluids.

| Groove Flanks B | ≤3.2 μm | ≤16 μm |
Note: It is recommended to have 50% to 90% of the working surface material contact area value.
INSTALLATION
Easily assembled into one-piece piston because the back-up rings are been produced in split forms. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.
Note: It is recommended to choose suitable material and quantity for guiding element regarding the purpose of application.
| PERMISSIBLE SEALING GAP | |
| Pressure (Bar) | Smax (mm) |
| P≤350 | 0.45 |
| 350< P ≤ 700 | 0.25 |
Note: The largest sealing gap value occurring on the non-pressurized side of the seal does have a vital importance for the function of the seal and in this respect it is quite important to use the S value lower than the above indicated numbers.
