Frequently Asked Questions

Q: What is Heldite Jointing Compound?
A: Heldite is a liquid compound which can be applied to most pipe joints either alone or in conjunction with a washer or a gasket. It will seal bolted, flanged or screwed joints. Heldite is non-abrasive and will not damage highly machines joint faces or such components as aluminium cylinder heads.
Q: What is the difference between Heldite Jointing Compund and others in the market?
A: Heldite is unique in the sealant formulation because of its combination of thermal, plastic and adhesive factors. Heldite’s inherent plasticity combats the effects of vibration and stresses imposed by temperature change or the assembly of dissimilar metals. The adhesive factor not only assists gasket location but in general practice has been shown to be an effective locking type sealant for imparting additional security to studs, splines and pressfit bearings.
Q: Is Heldite fully waterproof?
A: Yes, Heldite is completely waterproof and unaffected by sea water. The product is widely used for protecting electrical joint boxes and moisture sensitive instruments from the ingress of fluids or the effect of damp atmosphere.
Q: Can Heldite be used on everything?
A: Heldite is not compatible with ethanol because ethanol dissolves shellac, an ingredient in Heldite. If petrol sold at the pumps contains ethanol, then Heldite is not compatible with it. Heldite is not for drinking water (potable water) because it contains shellac and alcohol which allow bacteria to grow.
