AL-SAN LTD.

As high-performance plastics, we mainly use PTFE with various fillers such as bronze, glass fiber or carbon. For special applications, we also offer sealing rings made of PAI or PEEK.

We have specialized in R-rings SH according to DIN 34109 / DIN34110 / DIN34118. In addition to the hook joint (SH), we mainly supply with straight joint, overlapped joint (SU) or gas-tight joint (SG or SW).

From the compact DN50 to the robust DN700, these inserts ensure superior sealing performance and longevity. Crafted with precision engineering, each size guarantees optimal functionality in various applications. Choose reliability and durability across the spectrum with our DN50 to DN700 PEEK seat inserts, setting a new standard for valve efficiency. Size: DN50, DN80, DN100, DN150, DN200, DN250, DN300, DN350, DN400, DN500, DN600, DN700.

The X‑ring is a continuous, seamless vulcanized ring with a special profile which is derived from four O‑rings arranged in a square crosssection.The particular advantage of the X‑ring is that it cannot roll or twist. The squeeze required to maintain an effective seal is also relatively low.The X‑ring is used in mechanical and automotive engineering, preferably as a static radial or static axial seal. Other applications are for linear or rotary motion of plungers, pistons, tappets, dampers and valve, bearing and piston rods, etc.
