RKB7B7 – 7mm Barb x Barb Coupler for Micro-Tubing
The RKB7B7 is a 7mm barb-to-barb insert coupler for joining or splicing sections of 7mm micro-tubing. Its larger 7mm diameter allows higher flow rates than 1/4" (5mm) fittings and creates a tighter, more secure seal with 7mm tubing. Use the 4mm blue handle punch tool (RKP4) to punch clean installation holes in mainline poly tubing.
Key Features
- 7mm barb on both ends — larger diameter than 1/4" fittings for greater flow capacity and tighter seal
- Straight coupler — joins, extends, or repairs 7mm micro-tubing runs
- RKP4 compatible — use the 4mm blue handle punch tool (sold separately) for clean hole insertion
