Warm the poly tubing in hot water for 30 seconds if it's a cold-day install (makes the insert push-fit easier). Push the barb fully into the poly so the pipe is seated past the last retention rib. Secure with a stainless steel hose clamp or pinch clamp positioned over the barbed section — tighten until the clamp screw is snug but not over-deformed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMale NPT thread end:\u003c\/strong\u003e 2 to 3 wraps of PTFE thread tape (white tape is correct for PVC-on-PVC; pink heavy-duty for metal-to-PVC) clockwise around the male threads.

PVC male threads will bottom out and the receiving female port (PVC or metal) can split if cranked too hard. Hand-tight + 1 to 2 wrench turns is the target; if the joint weeps, replace the tape and re-thread — don't keep tightening. Over-tightening is the #1 cause of cracked male-adapter joints in the field.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUse a strap wrench on the molded hex collar, not channel locks on the body:\u003c\/strong\u003e the hex is there for exactly this; channel locks on the PVC body itself concentrate stress and can crack the wall.\u003c\/p\u003e\n\u003ch3\u003eWhat’s in the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOne Spears 1436-010 1 in.
