J-B Weld JB Weld High Heat Syringe (50197UK)

Description

Genuine J-B Weld · Part no. 50197UK

Safety: Warning. Very toxic to aquatic life with long lasting effects. Read the label before use.

J-B Weld High Heat is a repair compound in a syringe for the hot parts of a car, rated to 287°C with a quoted bond strength of 4730 PSI. It patches exhaust pipes, rust holes and other components near heat, resists water and chemicals, and cures dark grey so it blends in with exhaust metal.

Good to know

• High Heat or ExtremeHeat? This one is for parts that get hot but not glowing, up to 287°C, such as pipework further back along the exhaust; for manifolds right at the engine, pick a filler rated much higher.
• Can it fix a rusty exhaust hole? Small holes in sound pipe, yes, once the rust is wire-brushed off and the metal is clean and dry; if the pipe crumbles when pressed, it needs replacing.
• How strong is the joint? Ample for patching and sealing, but don't use it to hold up a hanging exhaust in place of a broken bracket or rubber mount.

Which one?

For manifolds and the hottest parts, J-B Weld ExtremeHeat (37901UK) is rated to 538°C; for general metal repairs away from heat, J-B Weld Original Syringe (50165UK).
