This Tigre USA PVC insert elbow connects polyethylene (PE) pipe to a female pipe thread (FPT) fitting at a 90-degree turn. The barbed insert end pushes into the ID of black PE irrigation tubing and clamps in place, while the FPT side accepts a male brass or PVC nipple from a valve, manifold, or pump. Standard issue for residential and light-commercial irrigation, well discharge, and cold-water service lines.

• 3/4" FPT (female pipe thread) x barbed insert connection
• 90-degree elbow configuration
• PVC Type 1 construction - chemical and corrosion resistant
• Fits black polyethylene irrigation and potable water tubing
• Meets ASTM D-2609 standards for plastic insert fittings
• NSF 14 and NSF 61 certified for potable water
• For use with ASTM D 2104 Schedule 40 or SIDR pressure-rated PE pipe
• Cold water applications only

Installation Tip: Cut the PE pipe square with a tubing cutter or PVC shears. If the pipe is stiff (cold weather, recently uncoiled), dip the cut end in hot water for 30-60 seconds so the insert seats fully against the shoulder. Push the insert in by hand, then secure with a stainless worm-gear clamp or PE pinch clamp positioned over the second barb back from the shoulder. For buried or below-grade runs and agricultural mains, stack two clamps for redundancy. Wrap 2-3 turns of PTFE tape on the FPT side before threading on the mating brass or PVC fitting; hand-tighten then snug 1.5-2 turns past hand-tight - PVC threads strip easily if over-torqued.

Selection Tip: Match the elbow size to the polyethylene pipe's pressure-rated ID. Typical residential lateral between zone valves and rotor heads or impact sprinklers; standard for landscape irrigation. SIDR poly pipe (ID-controlled) and IPS Schedule 40 poly pipe (OD-controlled) both accept this insert; the difference shows up in the clamp diameter, not the fit. For sub-grade joints carrying drinking water, verify your local plumbing code - some jurisdictions require IPS Schedule 40 solvent-weld fittings on potable mains and limit insert fittings to irrigation laterals or unpressurized service.

Note: Insert fittings are rated for cold water service only - do not use on water heaters, solar loops, or hot water distribution. Insert connections have lower burst pressure than solvent-weld; keep this elbow on zone laterals, pump discharge, or unpressurized drain rather than the house service main. For hot water or chemically aggressive service, step up to brass insert fittings or switch the run to PEX or copper.
