Zodiac – 1½” threaded union set – R0597700

The Zodiac R0597700 is an original replacement 1½” threaded union set designed for use with Zodiac pool care equipment. Union sets are essential plumbing fittings that allow components such as pumps, filters, and chlorinators to be securely connected to pool pipework and then disconnected cleanly for maintenance, servicing, or replacement without disturbing the wider plumbing system. This threaded union set is manufactured to Zodiac’s exacting OEM standards, ensuring a precise, leak-free connection every time.

The 1½” pipe size is one of the most commonly used connection diameters in domestic and semi-professional pool installations throughout Europe. The threaded design means no specialist tools or adhesives are required for installation — the union halves are hand-tightened and sealed with an integrated O-ring or flat gasket to form a watertight joint. This makes the R0597700 particularly practical for periodic maintenance scenarios where quick and clean disconnection is a priority. The set typically includes both union halves and the necessary sealing components to complete the installation.

Compatibility and application

The Zodiac R0597700 threaded union set appears consistently across multiple Zodiac product catalogues from 2015 through to 2020, confirming its long-standing role as a genuine Zodiac spare part for pool equipment plumbing. It is intended for use with Zodiac-branded pool pumps, filter housings, salt chlorinators, and similar equipment that uses 1½” inlet or outlet connections. For installations requiring a larger bore, Zodiac also offers the R0598200 2″ threaded union set, making it straightforward to match the union to the actual pipe diameter used in a given installation.

This part is best suited to pool owners, pool maintenance professionals, and installers working on Zodiac equipment who need to replace worn, cracked, or leaking union fittings. It is ideal for above-ground and in-ground pool systems that use standard 1½” plumbing. Because this is a genuine Zodiac OEM component, it offers the highest level of compatibility assurance compared with generic aftermarket alternatives, reducing the risk of fit issues or premature failure.

Buying guidance

Before ordering, confirm that your existing equipment uses 1½” threaded unions. If your pipework or equipment connections are 2″, the R0598200 is the correct alternative. As a genuine Zodiac spare part, the R0597700 is a direct like-for-like replacement that maintains the integrity of your pool system’s plumbing. Keeping a spare union set on hand is a practical measure that minimises downtime during pump or filter servicing.
