Bk 505-040 Schedule 80 Pvc Nipple 1 in X 4 in

Product Description

The BK 505-040 is a Schedule 80 PVC threaded nipple used to connect sections of pipe in pressurized water and liquid distribution systems. Sized at 1 inch by 4 inches, it is manufactured to IPS (iron pipe size) standards and threaded to NPT (National Pipe Thread) specifications. The Schedule 80 wall thickness provides greater pressure tolerance compared to Schedule 40, making it appropriate for demanding plumbing and industrial fluid-handling applications. Plumbers and pipefitters install this nipple as a short connector between fittings, valves, and equipment in both above-ground and in-wall configurations. Thread sealant compound or PTFE tape should be applied before installation.

This nipple is suited for residential and light commercial plumbing, irrigation systems, pool and spa equipment connections, and industrial process piping where Schedule 80 PVC is specified. It handles transport of water and compatible liquids in systems where threaded PVC connections are preferred over solvent-weld joints. The 1-inch nominal diameter makes it a common size in supply lines, equipment bypass loops, and valve connections. It meets ASTM D1785 specifications for PVC pressure-rated pipe and fittings.

Key Features

• Schedule 80 wall thickness for higher pressure tolerance than Schedule 40
• IPS sizing with NPT threading for broad compatibility with standard pipe fittings
• Meets ASTM D1785 specifications for PVC pressure-rated applications
• PVC construction resists corrosion and chemical degradation in water service
• Accepts pipe thread compound or PTFE sealing tape for leak-free joints

Compatibility

Designed as an OEM-style replacement and standard-use fitting for Schedule 80 NPT-threaded PVC piping systems using 1-inch nominal pipe connections.

Installation Notes

Installation is performed by licensed plumbers or experienced pipefitters. Always depressurize and drain the system before removing or installing threaded nipples. Apply thread sealant compound or PTFE tape to the male threads before hand-tightening, then wrench-tighten to avoid cross-threading or over-torquing PVC threads. Follow local plumbing codes and IPC guidelines for approved applications and pressure ratings.
