Bk 404-180 Schedule 80 Pvc Nipple 3/4 in X 18 in Npt

Product Description

The BK 404-180 is a Schedule 80 PVC threaded nipple rated for transport of water and a wide range of compatible liquids in plumbing and industrial piping systems. Measuring 0.75 inches in diameter and 18 inches in length, it is sized to IPS (iron pipe size) standards and threaded to NPT (National Pipe Thread) specifications on both ends. Constructed from Schedule 80 PVC, the nipple offers greater wall thickness and pressure resistance compared to Schedule 40. Licensed plumbers and pipefitters are the typical installers. The part meets ASTM D1785 specifications.

This nipple is suited for residential and light commercial plumbing, irrigation, industrial fluid transfer, and chemical handling applications where PVC is an appropriate material selection. Its NPT threading makes it compatible with standard pipe fittings, valves, and couplings found in common supply lines. The thicker Schedule 80 wall is particularly useful in applications requiring additional mechanical strength or exposure to higher pressures than Schedule 40 can accommodate.

Key Features

• Schedule 80 PVC construction for increased wall thickness and pressure capacity versus Schedule 40
• Sized to IPS standards and threaded to NPT specifications for broad fitting compatibility
• Meets ASTM D1785 material and dimensional specifications
• Suitable for water and a wide variety of compatible liquid transfer applications
• Apply pipe thread compound or sealing tape to threads before installation

Compatibility

Designed as an OEM-style replacement or new-installation nipple for standard NPT-threaded Schedule 80 PVC piping systems. Compatible with any NPT-threaded fittings, valves, or couplings rated for Schedule 80 PVC pipe.

Installation Notes

Installation is typically performed by a licensed plumber in accordance with IPC requirements. Shut off water supply and depressurize the line before removing any existing fittings. Apply pipe thread compound or PTFE sealing tape to the threaded portion of the nipple before making connections. Do not overtighten PVC threaded joints, as excess torque can crack the fitting.
