Description
The polymer union is one of the most practical and widely used fittings in both irrigation and industrial piping systems. It allows fast, leak-free connection and disconnection of pipes or equipment without cutting or rotating the pipe itself. Vispar polymer unions are engineered for maximum strength, perfect sealing and exceptional value.
Polymer Union
The Vispar polymer union consists of three parts: male end, female end and union nut. Thanks to its full-plastic construction (UPVC or polypropylene), it is completely corrosion-proof and considerably lighter than traditional galvanized or brass unions. It can be opened and closed countless times without wear or loss of sealing performance.
