Rain Bird 1/4 in Drip Distribution Tubing — 250 ft UV-Resistant Polyethylene, Flexible

Rain Bird T22-250S is a 250-foot roll of 1/4" blank drip distribution tubing built from UV-resistant polyethylene for flexible, durable micro-irrigation runs.

This 1/4" distribution tubing is designed to serve as either the main line in compact drip systems or as a branch line from 1/2" tubing to deliver water to individual emitters, micro-bubblers, misters and sprays. The tubing combines vinyl-like flexibility with the strength of polyethylene, a textured finish for easier handling, and a unique micro-porous connection design that tightens around barbed fittings for secure joins. It resists chemicals, algae, and UV damage, and its compact coil stores neatly to reduce waste and simplify installation and storage.

How durable and weather-resistant is this Rain Bird tubing?

The T22-250S is formulated from UV-resistant polyethylene resin for long-term exposure above ground or buried below. Its construction resists algae growth and common chemicals used in landscapes, helping maintain flow and reducing maintenance needs.

• UV-resistant polyethylene resists sun degradation
• Chemical- and algae-resistant formulation for cleaner lines
• Rated to operate from 0 to 70 psi for broad system compatibility

Will this tubing work with my existing micro-watering components?

Yes — the 1/4" T22 tubing is compatible with most 1/4" barbed drip fittings and micro-watering devices on the market. It connects to emitters, micro-bubblers, misters and 1/4" emitter tubing, and pairs with Rain Bird fittings (sold separately) when you need couplings, elbows, tees or end plugs.

• Standard 0.25" outside diameter and 0.17" inside diameter
• Works with many third-party 1/4" barbed fittings and emitters
• Use with Rain Bird stakes, fittings and valve components for integrated systems

How easy is it to install and handle during setup?

The textured outer finish improves grip and speeds up making connections, while the tubing’s flexibility allows tighter turns with fewer elbows. The compact coil design keeps the roll manageable as you pull lengths off, and the micro-porous join feature causes the tubing to expand over fittings and contract afterward for a secure fit.

• Textured finish makes push-on connections quicker and neater
• High flexibility for tight curves, switchbacks, and narrow beds
• Coiled roll stays compact for easy unrolling and storage

What sizes and pressure limits should I expect?

This product is a 250-foot roll of 1/4" blank distribution tubing with a wall thickness of .04" and an operating pressure range up to 70 psi. Rain Bird also offers shorter roll lengths (50' and 100') if you prefer less tubing per package.

• Outside diameter: 0.25"; inside diameter: 0.17"; wall: .04"
• Operating pressure: 0 to 70 psi — exceeds many competitor specs
• Available also in 50' and 100' lengths (sold separately)

Who is this for: Landscapers, gardeners, and homeowners designing small drip systems or extending 1/2" distribution lines will find the Rain Bird T22-250S especially useful. It suits tight planting areas and curved runs where flexibility, secure connections and UV resistance matter, and it integrates easily with standard 1/4" micro-irrigation parts for low-profile, efficient watering layouts.
