2" x 1-1/2" SP x FPT Reducer Bushing PVC SCH 40

Technical Specifications

This 2" × 1-1/2" SP × FPT Schedule 40 PVC Reducer Bushing is built for dependable performance across a range of plumbing and irrigation systems. It’s made from Schedule 40 PVC, a material chosen for its strength, corrosion resistance, and long service life in real field conditions. Crews who work on residential upgrades, commercial build-outs, and light industrial water systems use this type of fitting because it holds up well under typical working temperatures and low-pressure applications.

Key specs include:

• Nominal Pipe Size: 2" × 1-1/2"
• Material: Schedule 40 PVC
• End Type: Spigot × Female Iron Pipe Thread (FIPT)
• Max Service Temperature: 140°F
• Listings: NSF 14/61 for potable water
• Standards: ASTM D1784
• Part Number: 438-251
• Product Family: Schedule 40 PVC fittings

Specifications help installers match the correct component to their system layout and confirm that the reducer works with standard U.S. pipe sizing, common solvent-weld fittings, and threaded accessories used throughout residential and commercial plumbing.

Typical Applications

A 2” to 1-1/2” PVC Reducer Bushing is used daily in settings where crews need to transition from a larger spigot connection to a smaller threaded connection. This size is common in remodels, service calls, and new system layouts. You’ll often find it in:

• Home and commercial plumbing systems
• Irrigation and sprinkler lines for landscaping
• Pool circulation and spa equipment
• Filtration and water treatment setups
• Agricultural water supply lines
• Low-pressure industrial equipment that uses PVC for chemical and corrosion resistance

Many field technicians also use this bushing when connecting threaded valves, hose bibbs, risers, pressure gauges, or threaded adapters. For example, a 2" manifold feeding a 1-1/2" threaded ball valve is a common setup in irrigation and water distribution. This reducer bushing supports that type of transition without adding bulk or weight.

Installation and Handling Tips

A proper installation starts with clean materials. To begin, wipe the spigot end and the socket fitting to remove dust or moisture. Once the surfaces are ready, apply PVC primer followed by solvent cement. Insert the spigot end fully into the 2" socket fitting and allow the cement to bond according to the recommended cure time on the product label.

For the threaded side, wrap the FIPT end with PTFE thread seal tape. Hand-tighten first, then use tools to secure the joint without forcing the threads; overtightening can shorten the life of the fitting. Stick to temperature and pressure ratings listed for Schedule 40 PVC to maintain long-term reliability.
