Dura Plast 329-011 Coupling Manifold 1 in Slip X Swivel

Product Description

The DURA PLAST 329-011 is a 1-inch slip by swivel coupling designed for use in manifold plumbing systems. It connects fixed piping on the slip end to a rotating swivel fitting on the outlet side, allowing for easier alignment and reduced installation stress in tight or multi-branch configurations. Licensed plumbers and irrigation technicians install this type of fitting in both residential and light commercial applications where manifold layouts require flexible connection points. The slip end accepts standard 1-inch pipe, while the swivel end rotates freely to ease thread engagement with mating components.

This coupling is suited for manifold system installations where branch lines must connect to a central supply header. Typical applications include irrigation manifolds, pool and spa plumbing distribution headers, and similar multi-outlet supply configurations. The swivel design reduces the need to rotate the pipe itself during assembly, which is especially useful in confined mechanical areas or where multiple fittings are installed in close proximity.

Key Features

• 1-inch slip inlet for solvent-weld connection to standard PVC pipe
• Swivel outlet allows rotational adjustment during installation to ease alignment
• Manifold-system design supports multi-branch plumbing configurations
• Compact coupling profile suited for tight installation spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch manifold plumbing systems using standard slip and swivel connection interfaces.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements. Solvent-cement the slip end to clean, deburred pipe using the appropriate PVC primer and cement for the service environment. Shut off and depressurize the supply line before beginning any fitting work. Do not over-torque the swivel connection, as plastic fittings are susceptible to thread damage from excessive force.
