Value Collection 4SPU11/4 Pipe Coupling 1-1/4 in 304 Ss

Product Description

The VALUE COLLECTION 4SPU11/4 is a threaded pipe coupling designed for joining two sections of pipe in a straight run. Constructed from 304 stainless steel, it offers solid corrosion resistance in a wide range of fluid and gas handling applications. The fitting uses female National Pipe Taper (FNPT) connections on both ends and is rated for service up to 150 psi. Sized at 1-1/4 inches, it fits Schedule 40 pipe of the same nominal size. Plumbers, pipefitters, and mechanical contractors install this type of coupling during new construction, system repairs, and piping modifications.

This coupling is suited for residential and light commercial plumbing, HVAC hydronic piping, industrial fluid transfer, and general mechanical piping systems where stainless steel is specified for corrosion resistance or sanitary requirements. The FNPT x FNPT configuration requires compatible male-threaded pipe ends and appropriate thread sealant or tape for a pressure-tight joint. It performs reliably in water, air, and many chemical service lines where 304 stainless is an approved material.

Key Features

• 304 stainless steel construction for corrosion resistance in wet and chemical environments
• FNPT x FNPT threaded ends for standard tapered pipe thread connections
• 150 psi pressure rating for Schedule 40 piping systems
• 1-1/4 inch nominal size fits standard Schedule 40 pipe
• Straight coupling design for in-line pipe joining without directional change

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/4 inch Schedule 40 threaded piping systems requiring FNPT x FNPT connections.

Installation Notes

Installation is performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC piping codes. Shut off system pressure and drain the line before removing or installing any fitting. Apply thread sealant tape or compound to the male pipe threads before engagement — do not apply sealant to female threads. Tighten to hand-snug plus a wrench turn appropriate for the pipe material, then pressure-test the joint before returning the system to service.
