CHETRALON

100% pure, virgin moldable PTFE sealing cord

Round cord, various Dimensions
12 rolls per box
Dimensions (Ø x length); 2.4 mm x 15.3 m
4 mm x 10.7 m; 5.6 mm x 4.6 m; 7.1 mm x 2.7 m

Round mouldable PTFE sealing cord for valves, fittings etc.

CHETRALON replaces conventional square packing: simply wrap it in the stuffing box space and with goggle/cap nut tighten (50% compress).

"Immediate" gasket made to measure: easily formable PTFE core, supported by PTFE spiral wrapping, ensures adaptable filling of the sealing space while limiting cold flow – thus no pressing out of the material or "clogging" of the spindle.

universally applicable in the chemical, pharmaceutical, mechanical engineering, heating systems, building services, agricultural sector, steam applications and many more
