Barbed Couplers

Create a secure, leak-proof connection in seconds with our comprehensive selection of Barbed Couplers. As the simplest and most cost-effective solution for joining or repairing polyethylene drip tubing, these insert fittings are an essential component for any irrigation system. Whether you're fixing an accidental cut in your mainline, extending a drip line to a new garden bed, or connecting micro-tubing to your supply line, a barbed coupler provides a reliable, water-tight seal. Forget complicated tools and messy glues; the intuitive push-on design makes installation straightforward for DIY gardeners and efficient for professional landscapers.

Why Choose Barbed Couplers?

• Simple, Fast Installation: Simply push your poly tubing over the sharp barbs for a secure, friction-tight fit. For most low-pressure drip systems, no tools are required.
• Durable & Long-Lasting: Constructed from high-quality, UV-resistant Schedule 40 PVC plastic, our barbed fittings are built to withstand the harsh conditions of underground burial for years of reliable service.
• Versatile for Any Project: With a huge range of sizes from 1/4" micro-fittings to heavy-duty 2" couplers, we have the right connector for every application, from small home gardens to large agricultural operations.
• The Most Economical Repair: Don't replace an entire roll of tubing because of one leak. A barbed coupler is the most affordable way to make a permanent, reliable repair and get your system back up and running.

Finding the Right Barbed Coupler

We offer a variety of barbed couplers to meet the specific needs of your project.

Heavy-Duty Dura Barbed Couplers

Ideal for connecting mainline poly tubing, these robust couplers are made from thick Schedule 40 PVC. For systems operating at pressures above 20 PSI, we recommend securing the connection with a hose clamp for a guaranteed long-term seal.

• Common Sizes: 1/2", 3/4", 1", 1 1/4", 1 1/2", 2"

Economy Line Barbed Couplers

Perfect for most standard, low-pressure drip irrigation systems, these lighter-duty fittings feature a double-barb design that provides a secure connection up to 20 PSI without the need for hose clamps.

• Common Sizes: 1/2", 3/4"

1/4" Transfer Barbs & Micro-Couplers

These small but essential fittings are the backbone of any micro-irrigation system. Use them to connect two ends of 1/4" micro-tubing or soaker line together, or use a single barb to connect your 1/4" line directly to a hole punched in your 1/2" or larger mainline tubing.

• Compatibility: Fits 1/4" poly and vinyl tubing (.170" ID)

Barbed Reducing Couplers

Easily transition between two different sizes of poly tubing with a reducing coupler. These are perfect for stepping down from a larger mainline to a smaller sub-line within your system.

• Popular Configurations: 3/4" x 1/2", 1" x 3/4", 1" x 1/2"
