438-168 1 1/4" x 1 Sp x Fpt Reducer Bushing PVC SCH 40

Technical Specifications

This 1-1/4" x 1" SP x FPT Reducer Bushing offers a secure and reliable way to transition from a 1-1/4-inch spigot connection to a 1-inch female pipe thread. Made from durable Schedule 40 PVC, it provides long-lasting performance in residential, commercial, and light industrial plumbing systems.

Key Specifications:

• Nominal Sizes: 1-1/4" x 1"
• Connection Type: Spigot (SPG) × Female Pipe Thread (FPT / FIPT)
• Material: Schedule 40 PVC
• Color: White
• Maximum Service Temperature: 140°F
• Pressure Rating: Matches typical SCH 40 ratings (approx. 150–450 PSI based on system; threaded ends may reduce pressure capacity)
• Listings: NSF-approved for potable water applications
• Compliance Standards: ASTM D1784
• Part Number: 438-168
• Product Family: Schedule 40 PVC

The bushing’s threaded end supports easy attachment to valves, adapters, risers, or other 1" threaded components, while the spigot end fits cleanly into matching 1-1/4" socket fittings for a smooth, watertight transition.

Typical Applications

1-1/4” to 1” reducer bushings are seen across a wide range of water-handling systems. Particularly, they’re used where a precise size transition and dependable seal are non-negotiable, such as:

• Irrigation Systems: Connects PVC lines to sprinkler risers, threaded fittings, and irrigation accessories.
• Pool and Spa Plumbing: Helpful for pumps, heaters, chlorinators, and return lines needing a step-down bushing.
• Residential & Commercial Water Distribution: Eases transitions between fixture valves, manifolds, and system branches.
• Low-Pressure Industrial Water Lines: Suitable for cooling systems, utility water, and non-corrosive fluid loops.
• Agricultural Watering Systems: Connects drip manifolds, irrigation heads, and feed lines with threaded outlets.
• Landscape and Turf Equipment: Secures thread-to-socket transitions in outdoor water systems.

Threaded FPT connections are especially valuable in applications that require frequent disassembly, component replacement, or directional adjustments.

Installation & Handling Tips

Installing this reducer bushing is relatively straightforward, but proper handling helps maintain performance and lengthen service life.

Installation Steps

• Spigot End (1-1/4"): Insert into a matching socket fitting using PVC primer, followed by solvent cement. Confirm full engagement for a watertight seal.
• Threaded End (1"): Apply PTFE tape or a PVC-approved thread sealant to the male threads of the component being attached.
• Tightening: Hand-tighten, then add a half-turn with a wrench. Avoid overtightening, as it can damage the fitting and reduce lifespan.
• System Start-Up: Allow the proper cure time for solvent cement before pressurizing the system.

Best Practices

• Keep threads aligned to avoid cross-binding.
• Do not use with hot water, compressed air, or high-pressure chemical systems.
• Inspect fitting surfaces for debris or any imperfections ahead of installation.
• Use appropriate plumbing tools to work safely in confined spaces or hard-to-reach areas.

Following these guidelines reduces installation errors, prevents leaks, and ultimately supports long-term reliability in plumbing, HVAC, and irrigation systems.
