Durable Pro-Trade spiral barb couplings for 1/2 in. swing pipe and polyethylene tubing. Made from acetal for strength and dimensional stability, this 10-pack provides reliable push-fit connections for irrigation and low-pressure fluid systems.

  • Acetal construction: Engineered plastic resists cracking, offers rigidity and long service life.
  • Five-barb profile: Five staggered barbs create a secure seal and reduce risk of blowouts.
  • Standard 1/2 in size: Fits 1/2 in. swing pipe and compatible flexible poly tubing.
  • No adhesives required: Simple push-and-twist installation—no clamps or glue needed for typical irrigation use.
  • Performance ratings: Rated to 140°F (maximum working temperature) and approximately 87 PSI maximum operating pressure.

Each bag contains ten couplings sized for common drip and sprinkler branch connections. Use these fittings to speed installations, replace worn fittings, or assemble temporary lines. For best results, ensure tubing is cut square, fully insert the barbed end, and inspect fittings periodically for wear in high-UV or chemically aggressive environments.

Frequently Asked Questions

What material is this coupling made from?
The coupling is molded from acetal (polyoxymethylene), chosen for strength, dimensional stability, and resistance to typical irrigation conditions.
How do I install the spiral barb coupling?
Trim tubing square, push the tubing fully onto the barb and twist slightly until it seats. No glue is required for standard installations.
What pipe size and tubing types are compatible?
Designed for 1/2 in. swing pipe and common flexible polyethylene tubing used in drip and sprinkler systems.
What are the temperature and pressure limits?
These couplings are rated to about 140°F maximum working temperature and roughly 87 PSI maximum operating pressure.
