Hi-Impact Insert Coupling 1"

Joining two lengths of 1" poly pipe is a basic but essential task, and the American Granby Hi-Impact 1" Insert Coupling does it cleanly and reliably. With an insert x insert design molded from high-impact PVC, it accepts a 1" poly or flexible line on each end, bridging two runs into one continuous, corrosion-proof connection that will not rust or seize over time.

Simple, durable pipe joining

Insert couplings are the workhorses of poly pipe systems, used to extend lines, repair breaks, and tie sections together quickly. Because this fitting is PVC, it will never rust or corrode, an advantage that pays off in buried lines, well systems, and water treatment plumbing where metal couplings can fail or fuse to surrounding fittings after years in the ground. The Hi-Impact formulation resists the cracking that can occur when poly pipe is forced over a barb.

• 1" insert x insert coupling in Hi-Impact PVC
• Joins two lengths of 1" poly or flexible pipe
• Corrosion-proof and rust-free construction
• Impact-resistant formulation resists installation cracking
• Ideal for extending, splicing, or repairing water lines
• Lightweight and economical for high-volume use

Slide a stainless clamp onto each pipe end before seating it fully over the coupling barbs, then tighten both clamps evenly for a secure, leak-free joint. Warming stiff poly pipe slightly with warm water can ease assembly in cold weather and reduce the force needed to seat the barb. After the system is pressurized, check both clamps and snug them if any weeping appears. For installers building or maintaining well, irrigation, or filtration systems, this Hi-Impact coupling is an inexpensive, dependable way to keep poly pipe runs connected and leak-free, whether you are running a new line or making a fast repair on an existing one.

Because couplings see heavy use in any poly pipe system, stocking several of these inexpensive, corrosion-proof fittings means you are always ready to extend a line or make a quick repair. Reliable and rust-free, the Hi-Impact 1" coupling is a basic but indispensable part of well, irrigation, and water treatment plumbing. Whether you are splicing a long buried run or quickly patching a damaged section, this corrosion-proof coupling restores a continuous, leak-free line with nothing more than two clamps and a few minutes of work.
