DIYers, homeowners, and small contractors who work with PVC water pipe systems need a straight coupling that seats firmly, seals completely, and holds up to everyday water pressure without special tools or adhesive prep beyond standard PVC cement.\u003c\/p\u003e\n  \u003cp\u003eThese PVC straight pipe fittings are rigid Schedule-equivalent couplings machined from white PVC (polyvinyl chloride) material. Each sleeve joint features a smooth internal bore sized to accept standard metric pipe ODs across nine size options — 20mm (~0.79 in), 25mm (~0.98 in), 32mm (~1.26 in), 40mm (~1.57 in), 50mm (~1.97 in), 63mm (~2.48 in), 75mm (~2.95 in), 90mm (~3.54 in), and 110mm (~4.33 in). Wall thickness and overall coupling length scale proportionally with pipe diameter. Available in packs of 1, 2, 3, 5, or 10 pieces to match your project scope.\u003c\/p\u003e\n  \u003cp\u003eTypical use cases include cold-water supply line repairs where a damaged pipe section needs bridging, residential and commercial drainage runs requiring a mid-run extension joint, and drip-irrigation or garden water pipe sleeve joints connecting lateral lines to mains. The uniform socket depth on both ends ensures consistent glue-up contact area for a leak-resistant bond on PVC straight pipe fittings used in low-to-moderate pressure water systems.\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 standard metric OD PVC pipe (20–110mm).
