Heldite Jointing Compound 250ml

Heldite Jointing Compound is a high-performance sealant for preventing leakage of Petrol, Diesel Fuel, Hydraulic Fluids, Oils, Paraffin, LPG’s, Water, Steam and Gases in all branches of Automotive, Auto mechanical, Electrical and General Engineering, Plumbing, Heating and Pipeline Services. Heldite is a thick liquid compound that can be applied to any joint either with or without a gasket.

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.

Being non-abrasive, suitable for use with metals, i.e. steel, aluminium and brass, in combination with dissimilar metals, rubbers etc. Also waterproof, inert and anti-corrosive. Suitable for use with oils, fuels, hydraulic fluids, non-potable water, gases and coolants. Unaffected between -40°C to +350 °C. Prevents electrolytic action from the effects of sea water.
