Once the solvent-welded joints have cured, bring the union faces together with the gasket in place and hand-tighten the union nut. Do not overtighten, and always follow the solvent cement manufacturer’s instructions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich size union fitting do I need for my pipework?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSelect the fitting size that matches the outside diameter of your metric PVCu pipe. For example, use a 25mm union for 25mm metric PVCu pipe. If you are unsure of your pipe size, measure the outside diameter carefully and refer to metric sizing rather than nominal bore descriptions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre these fittings suitable for hot water or chemical applications?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThese PVCu fittings are generally suitable for cold water and many non-aggressive chemicals within the temperature and pressure limits recommended for PVCu systems.
