3×1.5; 5×2; 7×2.5; 10×3; 14×5; 17×6; 20×7 mm

(Special dimensions on request)

– Joint sealant, with adhesive back for universal flange sealing in all industrial areas

– Economical flat sealing tape made of high-quality ePTFE (stretched, expanded material)

– Handy  & easy to install: no punching out, directly from the roll: round, square, longitudinal, uneven

– Universally applicable as static flat gasket in almost all areas, e.g. heat exchangers, pipelines/flanges, columns, housings – for steel flange, smooth or with tongue and groove – for oxygen lines in copper/copper alloys (see BAM approval)

– Due to the good formability especially suitable for FRP and plastic flanges, glass/graphite apparatus, sight glasses, ceramic flanges

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

Technical data:
pmax: 100 bar (depending on the mechanical conditions of the aggregate to be sealed)
t: -240° C to +270° C
pmax and tmax (oxygen): 50 bar – 150° C; 30 bar – 200° C
pH: 0-14 (except liquid oxygen, molten alkali metals, fluorine and various (rare) halogenated compounds)

Approvals/Tests/Correspondences:

CHETRA MPG

Moldable polymer seal

Product no. 900511

1 box:
2x comp. A (cartridge) 400 ml
2x comp. B (hardener) 185 g

– 2-component sealing material polymer (A) and hardener (B) for the production of flat gaskets of all shapes and sizes directly on the object to be sealed

– MPG is a high quality system for the production of flat gaskets for most industrial applications

– Flange unevenness up to 7 mm can be compensated: MPG is dimensionally stable, does not shrink or warp, does not slip

– easy assembly (see illustration) and disassembly – can be pulled off easily without jamming, protects flanges

– very economical in use: no waste, no cutting and punching

– Resistant to water, oils, hydraulic fluids, solvents, chemicals etc. (except concentrated acids/alkalis; (see pH range)

Technical data:
p-range: vacuum – 220 bar (see below)
pmax: (after full curing 2-3h): 220 bar (depending on mechanical conditions and the temperature to be bridged sealing gap)
pmax (immediately after application): 1 bar; pmax (steam): 7 bar
t: -50° C to +260° C; pH: 2-11
