Georg Fischer 861-133 Sch 80 Pvc Close Nipple 1 in Mpt

Product Description

The GEORG FISCHER 861-133 is a Schedule 80 PVC close nipple with male pipe thread (MPT) on both ends, designed for use in pressure piping systems where corrosion resistance and long service life are required. At 1 inch nominal pipe size, this close nipple provides a compact threaded connection between two female-threaded fittings or ports. Schedule 80 PVC wall thickness meets the demands of higher-pressure applications compared to Schedule 40, making it suitable for chemical, irrigation, and industrial fluid handling systems. Licensed plumbers and pipefitters install this component as part of threaded PVC assemblies.

This close nipple is used in residential and commercial plumbing, pool and spa piping, chemical distribution lines, and irrigation systems where a short threaded male-to-male connection is needed. Its PVC construction makes it appropriate for cold and ambient-temperature fluid service where metal corrosion or chemical attack on metal nipples is a concern. Typical installation connects two female-threaded valves, fittings, or equipment ports in tight-clearance locations where a longer nipple would not fit.

Key Features

• Schedule 80 PVC wall thickness rated for higher operating pressures than Schedule 40
• Close nipple configuration for minimal thread-to-thread spacing in tight installations
• MPT x MPT threading on both ends for direct connection to female-threaded fittings
• Corrosion-resistant PVC construction will not rust, pit, or scale
• Maintenance-free service life in compatible fluid and chemical applications

Compatibility

Designed as an OEM-style Schedule 80 PVC threaded fitting for use with standard 1-inch female NPT fittings, valves, and equipment ports in conforming PVC piping systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and applicable IPC requirements. Depressurize and drain the system completely before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape rated for PVC and the specific fluid service. Do not overtighten PVC threaded connections, as cracking or thread damage will result.
