The Silicone Lubricant for Underground Pipes & Fittings 1kg is an essential maintenance and installation aid formulated specifically to facilitate the smooth assembly of push-fit below-ground drainage systems. Manufactured from a high-grade, chemically stable silicone compound, this lubricant is engineered to remain effective in damp, cold, and demanding trench environments. Its specialized formulation is completely safe for use with unplasticized polyvinyl chloride (uPVC) pipes, fittings, and rubber ring seal joints, preventing degradation while ensuring long-term material compatibility.
 
Featuring a smooth, high-viscosity paste consistency, the lubricant dramatically reduces insertion friction when joining pipes and fittings, allowing spigots to slide effortlessly into socket seals. This effortless insertion protects the factory-fitted rubber rings from being dislodged, rolled, or damaged during installation, guaranteeing a secure, correctly seated, and permanently watertight joint. Furthermore, its water-resistant properties ensure that the lubricant will not easily wash away in wet ground conditions before backfilling takes place.
 
Supplied in a convenient 1kg container with a secure lid, this lubricant provides ample coverage for large-scale drainage installations as well as ongoing maintenance work. By eliminating the physical strain of forcing tight joints and preventing seal displacement, it saves valuable time on site and ensures professional-grade integrity across your entire drainage network.
