The NIBCO 474-007 is a PVC Schedule 40 Insert x Socket Adapter sized at 3/4 inches. It is a reliable transition fitting used in residential and commercial plumbing systems. Plumbers and pipefitters use this adapter to connect insert-style tubing, such as flexible polyethylene or poly pipe, to a standard PVC socket connection. This makes it easy to transition between pipe materials without the need for specialized tools or adhesives on the insert side. The fitting is manufactured from Schedule 40 PVC, which means it has thicker walls and greater pressure tolerance compared to lighter-weight PVC fittings. Schedule 40 PVC is rated for cold and hot water distribution lines, irrigation systems, pool and spa plumbing, and general water service applications. The white PVC construction resists corrosion, scale buildup, and chemical degradation, making it a long-lasting choice for wet environments. The insert end grips the tubing firmly and is typically secured with a stainless steel clamp for a leak-proof seal. The socket end accepts standard PVC cement for a permanent, pressure-tight bond. At 3/4 inches, this adapter fits one of the most common pipe sizes used in residential supply lines, irrigation laterals, and light commercial plumbing runs. NIBCO is a trusted manufacturer in the plumbing and flow control industry, known for producing fittings that meet ASTM and NSF standards. Trade professionals rely on NIBCO Schedule 40 fittings for consistent dimensions and durable performance across a wide range of piping systems.
The NIBCO 474-007 offers a dependable, corrosion-resistant connection point between insert tubing and socket PVC pipe. It is a go-to fitting for plumbers working on irrigation, water supply, and pool or spa installations.
