Zodiac – Metric tailpiece 63/50mm union kit (x2) – R0728700

This is a genuine Zodiac replacement union tailpiece kit, reference R0728700, supplied as a set of two metric tailpieces designed for 63/50 mm pipe connections. These fittings form the hydraulic interface between the pump body and the pool pipework, allowing the pump to be securely and leak-free connected to the circulation system. As an official Zodiac spare part, this kit ensures a precise fit and reliable sealing performance identical to the original factory-fitted components.

Union fittings are a critical element in any pool pump installation. They allow the pump to be disconnected from the plumbing quickly and without cutting pipework — essential for maintenance, winterisation, or pump replacement. The tailpiece is the threaded or barbed section that bonds to the pipe, while the union collar locks onto the pump housing. This kit supplies two tailpieces, covering both the inlet and outlet sides of the pump in a single purchase.

Technical characteristics and compatibility

The tailpieces in this kit are sized for 63/50 mm metric pipework, which is the standard pipe diameter widely used in European pool installations. The 63 mm dimension refers to the outer pipe diameter, while 50 mm corresponds to the inner bore, making these fittings compatible with the most common pool plumbing standard across continental Europe and the UK. The kit is supplied without locking rings, so if locking rings are also required they must be sourced separately.

This kit is confirmed as a genuine spare part compatible with the Zodiac E30iQ pump, as well as other Zodiac FloPro series pumps that use the same union connection standard. The fittings are manufactured to Zodiac’s original specifications, ensuring correct torque, sealing geometry, and dimensional accuracy. Using genuine parts avoids the risk of misalignment or premature seal failure that can result from non-original alternatives.

Suitability and buying context

This union tailpiece kit is intended for pool owners and installers working with Zodiac E30iQ or compatible FloPro pumps who need to replace worn, cracked, or leaking tailpiece fittings. It is equally useful during a pump swap where the existing tailpieces are in poor condition and need renewal before refitting. Because the kit contains two tailpieces, both the suction and return sides can be refreshed simultaneously, which is best practice during any pump service. This product is suitable for in-ground and above-ground pool installations using 63/50 mm metric PVC pipework, which covers the majority of residential pool plumbing in Europe.
