Schedule 80 PVC female adapter transitions from solvent-welded PVC pipe to a threaded male fitting - one end is a slip socket for cementing onto Schedule 80 or Schedule 40 PVC pipe, the other end is an internal FPT (Female Pipe Thread, NPT) socket for screwing a brass valve, threaded pipe, or other male-threaded component into. The heavy-wall Schedule 80 body handles higher working pressures than standard Schedule 40 - the right choice for industrial water systems, irrigation pressure lines, chemical handling, and any pressure application that benefits from a removable threaded joint.

• Size: 1" slip x 1" FPT (NPT)
• Schedule 80 heavy-wall construction - higher pressure rating than Schedule 40
• Dark gray PVC body, UV resistant for outdoor exposure and easy visual identification vs white Schedule 40
• Slip end: solvent weld with PVC cement rated for Schedule 80 (typically gray-bodied cement)
• FPT end: standard NPT thread, accepts brass, plastic, or steel male threaded fittings up to 1" MPT
• Meets ASTM D2467 (Schedule 80 PVC pressure fittings)
• NSF Listed for potable water applications
• Working temperature: up to 140 deg F (PVC limit; use CPVC for higher temps)

Tip: Never apply solvent cement to the threaded FPT end - threads seal mechanically with PTFE tape (2-3 wraps clockwise on the male threads) or pipe-thread sealant. Over-tightening plastic threads cracks the female socket; hand-tighten plus one to one-and-a-half turns with a wrench is the rule. Schedule 80 fittings accept Schedule 40 pipe of the same nominal size since the outside diameter is identical between schedules.
