Whether you are building a recirculating fish pond, a garden irrigation network, or an industrial fluid-distribution line, these PVC cross 4-way solvent weld pipe fittings give you a leak-free, rigid junction that holds pressure without flex or creep.\u003c\/p\u003e\n    \u003cp\u003eEach fitting is moulded from rigid white PVC (polyvinyl chloride) and accepts standard solvent-weld cement for a permanent, chemical-fused bond. The range covers equal-bore sizes from 20 mm (approx. ¾ in) up to 160 mm (approx. 6¼ in), plus reducing cross options at 75×32 mm, 90×32 mm, and 110×32 mm for branch-line step-downs — all sold individually so you order exactly what you need.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include koi pond and aquaculture filtration manifolds, drip-irrigation and sprinkler distribution headers, workshop compressed-air ring mains, and light-duty industrial process pipework where a four-way branch point is required. Long-tail use cases such as \"PVC cross fitting for fish pond filter\" and \"4-way solvent weld pipe junction industrial\" are served across the full size range.\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 Fits standard metric PVC pressure pipe (Class C \/ Class D) and equivalent schedule pipe with matching outside diameter.
