B38;K Llc 506-040 Pvc Schedule 80 Nipple 1-1/4x4 in

Product Description

The B38;K LLC 506-040 is a Schedule 80 PVC nipple sized at 1-1/4 inches in diameter by 4 inches in length. Schedule 80 PVC carries a heavier wall thickness than Schedule 40, making it suitable for higher-pressure applications and installations that require added mechanical strength. This nipple serves as a short threaded connector between fittings, valves, pumps, and piping assemblies. It is installed by licensed plumbers and qualified trade professionals in both residential and light commercial systems where corrosion resistance and chemical compatibility are required.

This nipple is used in plumbing, pool and spa circulation systems, irrigation, and industrial process piping where PVC is an approved material. The 1-1/4-inch pipe size fits common pump suction and discharge lines, filter manifolds, and valve configurations. Its 4-inch body length provides a standard close-nipple extension between components without requiring a union or coupling cut-in.

Key Features

• Schedule 80 PVC construction for higher pressure and impact resistance versus Schedule 40
• 1-1/4-inch nominal pipe size fits standard NPT fittings and valves
• 4-inch body length suits close-coupled piping configurations
• Corrosion-resistant PVC material compatible with a wide range of chemicals and water treatment compounds
• Threaded ends for tool-installed connections without solvent cementing at the joint

Compatibility

Designed as an OEM-style replacement or new-installation component for 1-1/4-inch Schedule 80 PVC piping systems in plumbing, pool, spa, and irrigation applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified tradesperson in accordance with applicable IPC or local plumbing codes. Shut off and depressurize the system completely before removing or installing threaded nipples. Apply an approved thread sealant tape or compound to the male threads before assembly and tighten with strap wrenches to avoid cracking the PVC body. Do not use pipe wrenches directly on the PVC without protective padding, as overtightening can fracture Schedule 80 fittings.
