These dark PVC transitional socket adhesive fittings are designed for DIYers, plumbers, and irrigation installers who need a dependable solvent-weld slip joint that holds under pressure without special tools.\u003c\/p\u003e\n\u003cp\u003eEach fitting is molded from rigid dark PVC (polyvinyl chloride) and accepts standard solvent cement for a permanent, watertight bond. Available in six sizes spanning 20 mm (approx. ¾\") through 63 mm (approx. 2\"), with socket depths typically ranging from 20 mm to 63 mm to match the pipe OD. Wall thickness is proportional to pipe diameter and conforms to standard schedule ratings.\u003c\/p\u003e\n\u003cp\u003eTypical applications include residential and commercial irrigation lateral lines, above-ground and below-ground drainage runs, pool and spa plumbing transitions, and workshop compressed-air distribution where a schedule-to-schedule diameter change is required.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for use with standard PVC pipe of matching nominal diameter.
