## Summary description

WAVIN double nipple ¾" x ½" designed for use with union/union-nut connections on both ends. The fitting provides a straight adapter between pipes or fixtures with differing thread or diameter sizes and is suitable for plumbing repairs, installations and replacements. Intended for domestic and light commercial water supply applications where a compact, threaded inline connector is required.

## Long description

The WAVIN ¾" x ½" double nipple fitting for union connections is a compact inline adapter that connects two union-nut style fittings with differing thread sizes. Constructed with a combination of brass and engineered plastic, this straight adapter creates a secure, threaded link between components in domestic and light commercial water supply systems. It is intended for straightforward plumbing repairs, fixture installations and replacements where a short, reliable connector with both ¾" and ½" union interfaces is required.
Advantages
The combination of brass and plastic in the WAVIN double nipple balances corrosion resistance and mechanical strength while keeping weight and cost moderate. Its union-nut compatible ends simplify installation and removal without the need for soldering or adhesive joint work. The straight, inline design minimizes flow disruption and fits into tight spaces where a short threaded connector is preferable.
Suitable for
Connecting fixtures and pipework with ¾" and ½" union-nut thread interfaces
Repairing domestic water supply lines and replacing damaged connectors
Plumbing installations in bathrooms, kitchens and utility rooms
Light commercial plumbing applications where a compact threaded adapter is needed
Key specifications
Connection type: double nipple with union-nut compatible ends
End sizes: ¾" and ½" union interfaces
Material: brass components combined with engineered plastic elements
Design: straight, inline adapter to maintain flow alignment
Application: cold and hot water supply in domestic and light commercial settings
How to use
Shut off the water supply and relieve pressure before beginning work. Thread the ¾" end and the ½" end into their respective union-nut fittings by hand to start, then tighten with an appropriate wrench until a secure, leak-free seal is achieved; avoid over-tightening to prevent damage to threads or plastic parts. If seals or washers are required by the existing fittings, ensure they are correctly positioned before final tightening. After installation, slowly restore water flow and check for leaks at both connections.
Usage recommendations
Use this WAVIN ¾" x ½" double nipple in accessible locations where periodic inspection is possible; avoid exposing the plastic components to prolonged UV or aggressive chemical environments. Select compatible sealing washers and apply standard plumbing practice when connecting to different materials to ensure a durable, leak-free joint.
