1 inch x 3/4 inch PVC Schedule 40 Reducing Adapter Fitting x Male

1 inch x 3/4 inch PVC Schedule 40 Reducing Adapter – Slip x Male Thread

The 1 inch x 3/4 inch Schedule 40 PVC reducing adapter is a transition fitting designed to connect a 1 inch socket (slip) end to a 3/4 inch male NPT threaded connection. Used in pressure and non-pressure systems, it supports dimensional transitions in cold water distribution, irrigation, and utility piping layouts.

Key Technical Advantages

This fitting is fabricated to meet applicable standards for dimensional consistency and material performance in rigid PVC piping systems. Common field-use benefits include:

• ✅ Schedule 40 Design Suitable for pressurized systems when solvent welded properly and used within temperature and pressure limits.
• ✅ Slip x MPT Configuration Provides solvent weld connection on the 1 inch end and a mechanical threaded joint on the 3/4 inch side for connection to valves, risers, or other components.
• ✅ Rigid PVC Construction Resistant to corrosion, scale, and chemical degradation, making it ideal for water and non-corrosive fluid systems.
• ✅ Meets NSF and ASTM Standards Manufactured in compliance with ASTM D2466 and NSF-certified for potable water applications.

Specification Overview

• Material: PVC (Polyvinyl Chloride)
• Size: 1 inch Slip x 3/4 inch Male NPT
• Schedule: 40
• Standards: ASTM D2466, NSF 61 & 372 (lead-free)
• Application: Pressure-rated cold water distribution, irrigation, and utility connections

Installation Guidelines

Solvent weld the slip end using approved primer and cement according to pipe manufacturer recommendations. Ensure full insertion to the socket stop. For the threaded end, use PTFE thread tape or appropriate thread sealant to prevent leaks—avoid overtightening to protect thread integrity. Allow proper curing time for solvent weld joints before pressurizing the system.

Typical Use Cases

This reducing adapter is used in both residential and commercial systems to connect different pipe sizes without the need for bushings or couplings. Ideal for irrigation manifolds, pump assemblies, water service risers, and other installations requiring dimensional transitions with a threaded outlet.

Compliance Insight

As required by the Safe Drinking Water Act (SDWA), all fittings intended for potable water use must meet lead-free standards. This Schedule 40 PVC fitting meets NSF 61 and 372 certifications and is suitable for use in regulated applications.

The 1 inch x 3/4 inch PVC Schedule 40 Reducing Adapter provides a durable and code-compliant solution for size reduction in rigid plastic piping systems. Its slip x male thread configuration offers installation flexibility in both new and retrofit plumbing layouts.
