Heldite Jointing Compound

Jointing compound for use to help prevent leaks of petrol, diesel, lubricating and transmission oils, heating oil, paraffin, water (including sea water), steam and other gases. Resistant to temperature and pressure variations.

It will effectively seal bolted, flanged or screwed joints and as it is in a liquid form it is economical to use and does not tend to squeeze out into the interior of a joint and cause damage. Heldite is non-abrasive and will not damage highly machined joint faces; the combination of thermal, plastic and adhesive factors in this jointing compound is unique in the sealant formulation. The plasticity combats the effects of temperature and pressure changes, shifting levels and stresses associated with the assembly of dissimilar metals such as aluminium housings bolted to cast blocks. The adhesive factor not only assists gasket location but has been shown to be an effective locking sealant for imparting additional security to splines, studs and press fit bearings.
