A barbed insert-to-Male NPT adapter used to terminate flexible polyethylene (PE) pipe into any female-threaded fitting, valve, or pump port. The barbed insert end accepts 2" polyethylene tubing; threaded end is a 2" Male NPT. Common in residential irrigation, well-service lines, sprinkler manifolds, and low-pressure agricultural water systems.

• Nominal size: 2"
• Connection: 2" barbed insert x 2" MPT (Male NPT)
• Rigid PVC body resists chemical attack and will not corrode like brass or galvanized fittings
• Stepped barbs grip flexible poly tubing under stainless-steel hose-clamp pressure
• Cold-water service only - not for compressed air, gases, or hot-water lines
• ASTM D-2609 listed; NSF 14 and NSF 61 compliant for potable water

Installation Tip: Warm the end of the poly pipe in hot water for 15-20 seconds before pushing the barbed adapter in - the pipe slides on cleanly and seals tighter as it cools around the barbs. Finish with a stainless or coated worm-gear clamp positioned squarely over the barb section, not behind it. Use PTFE tape on the MPT threads when joining to a metal fitting.
