Raindrip Pipe Thread Compression Swivel Adaptor - 1/2in Tubing - Bulk

Swivel Adaptor for Connecting 1/2in Poly Hose to Pipe-Threaded Valves

Plumbed valves, manifolds, and irrigation controllers use pipe thread (NPT) connections rather than the garden-hose thread found on outdoor taps, and mismatching the two leads to leaks or a fitting that won't seat. Raindrip's pipe thread swivel adaptor threads onto a 3/4in male pipe thread fitting and grips 1/2in poly hose at the other end, with a free-rotating body that keeps the tubing from twisting during installation.

This bulk pack suits professional installers and larger drip irrigation projects connecting poly hose to plumbed valve or manifold ports across multiple zones.

Key Features & Benefits

• 3/4in MPT to 1/2in tubing — connects 1/2in poly hose to 3/4in male pipe thread plumbing fittings or valves.
• Swivel design — rotates freely on the pipe thread connection for easy tubing outlet alignment.
• Compression grip — securely grips 1/2in poly hose for a reliable, leak-resistant seal.
• Includes filter washer — screens particulates before they enter the drip system at the connection point.
• Bulk pack — keeps professional installers stocked across multiple valve or manifold connections.

Who Should Use This

Irrigation installers and contractors connecting 1/2in poly hose to pipe-threaded plumbing connections, valves, or manifold ports in professional drip installations rely on this adaptor to bridge the two thread types.

Frequently Asked Questions

What is the difference between pipe thread and hose thread fittings?

Pipe thread (MPT/NPT) is used on plumbing fixtures, valves, and manifolds and has a tighter thread pitch than garden hose thread (MHT). This adaptor is built specifically for pipe thread connections rather than hose bibs.

How do I know if this adaptor fits my tubing?

The compression end accepts standard 1/2in polyethylene poly hose used in drip irrigation supply lines. Confirm your tubing's outer diameter matches before ordering.

Does this adaptor include a filter?

Yes, a filter washer is included to screen sediment at the inlet connection. It's a basic first line of defense that helps protect downstream emitters from debris.

Why buy this adaptor in bulk?

Bulk packs offer a better per-unit cost for professional installers who regularly connect poly hose to pipe-threaded fittings across multiple irrigation projects. A single homeowner installation typically doesn't need bulk quantity.
