DIYers, landscapers, and plumbing contractors working on irrigation grids, drainage manifolds, or utility pipe networks need a fitting that holds pressure, resists chemical attack, and bonds permanently with standard solvent cement. These gray PVC 4-way cross fittings deliver exactly that.\u003c\/p\u003e\n\u003cp\u003eEach fitting is molded from rigid gray PVC and uses a solvent-weld (Klebefitting) socket connection on all four ports. Available inner diameters span 20mm (approx. 3\/4 in), 25mm (approx. 1 in), 32mm (approx. 1-1\/4 in), 40mm (approx. 1-1\/2 in), and 50mm (approx. 2 in), covering the most common residential and light-commercial pipe schedules. Wall thickness and overall body dimensions scale proportionally with each size.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include garden drip-irrigation cross-distribution points, underground drainage junction boxes, workshop compressed-air ring mains, and pool or spa return-line manifolds — anywhere a single cross junction replaces two separate tees and reduces leak points.\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-wall gray PVC pressure pipe (PN10 \/ Schedule 40 equivalent).
