Water supply end caps deliver a high-strength, pressure-tight seal for terminating pipe runs or isolating pressure test sections. Injection-molded in our own factory, these caps feature a reinforced convex dome that distributes internal pressure evenly. Every unit passes strict dimensional inspection to ensure a snug, leak-proof solvent cement joint for long-term municipal and commercial water projects.
Reinforced Factory Molding: Engineered with extra wall thickness at the dome to withstand high static system pressures and water hammer shocks.
Tight Socket Tolerances: Machined mold cavities ensure precise socket taper and depth for maximum solvent-welded contact area.
Corrosion & Chemical Resistance: Completely unaffected by aggressive soils, water treatment additives, or environmental exposure.
Reliable Line Termination: Ideal for temporary pipeline pressure testing as well as permanent end-of-line closures.
