Zodiac - 2" union tailpiece kit (2 pieces) - R0771400

Zodiac – 2″ union tailpiece kit (2 pieces) – R0771400

The Zodiac R0771400 is a genuine replacement 2-inch union tailpiece kit containing two pieces, designed to maintain secure and leak-free hydraulic connections on Zodiac pool equipment. Union tailpieces are the threaded or barbed fitting sections that form the mechanical and watertight joint between plumbing pipework and pool devices such as pumps, filters, and chlorinators. Over time, these fittings can crack, deform, or develop leaks due to pressure cycling, UV exposure, and chemical contact, making a like-for-like OEM replacement essential for maintaining system integrity.

This kit supplies both tailpieces needed for a full union connection, meaning you can complete a repair or installation in a single purchase without sourcing individual components separately. According to official Zodiac catalogue documentation, if your plumbing uses 1½-inch pipework rather than 2-inch, two additional R0770300 adaptor pieces must be added to the installation alongside this kit, allowing the same union assembly to accommodate the smaller pipe diameter. The tailpieces are manufactured to Zodiac’s original specification, ensuring dimensional compatibility with the corresponding union body components in the Zodiac range.

Technical characteristics and compatibility

The kit is rated for 2-inch (DN50/63 mm) connections, which is a standard pipe diameter used widely in medium-to-large residential and commercial pool hydraulic circuits. The fittings are constructed from durable thermoplastic material resistant to pool chemicals, including chlorine and salt, as well as to the mechanical stresses of pressurised water systems. As genuine Zodiac spare parts, they are engineered to match the thread form, sealing surfaces, and torque specifications of the original union assemblies, preventing cross-threading or seal failures that can occur with non-OEM alternatives. The two-piece format of the kit covers both sides of a union joint, making it a complete solution for replacing worn or damaged tailpieces on a single connection point.

Suitability and application

This kit is intended for pool owners, installers, and service technicians who are maintaining or repairing Zodiac pool equipment that uses 2-inch union connections. It is suitable for both in-ground and above-ground pool installations where Zodiac pumps, filters, or ancillary equipment are plumbed using standard 2-inch pipework. For installations with 1½-inch pipework, the addition of R0770300 adaptors (sold separately, two required) allows the same assembly to function correctly. This is a straightforward maintenance spare that requires no specialist tools beyond standard plumbing practice, and fitting genuine Zodiac components ensures the long-term reliability of the hydraulic circuit without compromising warranty or system performance.
