Flexitallic Style R

Flexitallic Style R

Consists of a spiral-wound metallic strip in a deep «V» with a flexible filler. The inside and outside diameters are reinforced by several wraps of winding without filler, reinforced by a suitable number of spot welds. PMUC certified.

Flexitallic Style RIR

Flexitallic Style RIR

Comprises a spiral-wound part with an inner ring. The inner ring acts as a compression stop. By filling the annular space between the bore of the flange and the inside diameter of the gasket, it reduces the effects of turbulence of the fluids and prevents premature flange erosion. PMUC certified.

Supranite Packing 530

Supranite Packing 530

Consists of very thin filaments of spectroscopically pure PTFE. Features outstanding chemical compatibility as it contains no other lubrification compound (oil,…) than pure PTFE dispersion.

More Details »
Supranite Packing 850

Supranite Packing 850

Produced by braiding pure calcium silicate yarn. The absence of an organic support in the production of these yarns results in a much smaller loss of volume at high temperatures than with most other products.
