The Blazing BLZ 1429-010 is a fast-fitting 1" x 1" standard insert coupler engineered for quick, reliable connections on 1" NSF poly pipe. Ideal for irrigation and low-pressure dis tribution, this coupler delivers consistent flow with a simple insert-style installation that requires minimal tools. Compatible with any manufacturer’s 1" 80#, 100#, or 160# NSF poly pipe for secure insert connections. 1" x 1" insert configuration provides a straightforward coupling solution for like-sized poly pipe runs. Suggested operating pressure range: 10–80 psi for typical irrigation and drip systems. Burst pressure exceeds 450 psi — not intended for use on main lines or under constant pressure systems. Flow rates and friction loss comparable to traditional insert fittings; designed to maintain system performance. Durable design for outdoor irrigation use and routine residential or commercial landscape applications. Use this coupler where a fast, dependable join is needed between two lengths of 1" NSF poly pipe. For best results, ensure pipe ends are clean and cut square, push the insert fully into the fitting, and test the line at low pressure before returning to normal operating pressure. Show more
