Dura Plastic 8058-010 Pvc Union 1 Inch Fnpt Sch 80

Product Description

The DURA PLASTIC 8058-010 is a Schedule 80 PVC union fitting with a 1-inch nominal size and female NPT (FNPT) end connections. It uses an FKM O-ring seal to provide a reliable, leak-resistant joint that can be broken and reconnected without cutting pipe. Schedule 80 wall thickness makes this union suitable for higher-pressure applications compared to standard Schedule 40 fittings. Plumbers and pipefitters install this type of union where a removable connection point is required in a PVC piping system, such as at pumps, valves, or equipment that may need periodic service or replacement.

This union is suited for residential and commercial plumbing, irrigation, chemical processing, and industrial fluid-handling systems where PVC is the specified pipe material. The FNPT end style allows threaded connection to Schedule 80 PVC pipe or fittings. The FKM O-ring provides broad chemical compatibility, making this fitting appropriate for systems handling water, mild acids, bases, and a range of industrial fluids. It is a domestically manufactured fitting intended for permanent installation with periodic disconnect capability.

Compatibility

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ASTM standards for PVC pressure piping. Shut off and depressurize the system completely before disassembling or installing this union. Use appropriate thread sealant rated for PVC and compatible with FKM on the FNPT connections. Do not over-torque threaded PVC connections, as PVC is susceptible to cracking under excessive mechanical stress.
