Bk 496-153 Toilet Supply Connector 1/2 Fip X 7/8 Bc Nut 20 In.

Product Description

The BK 496-153 is a braided stainless steel toilet supply connector designed to deliver a reliable water supply connection between a shutoff valve and a toilet fill valve. The core is virgin PVC reinforced with polyester yarn braiding, then over-braided with 304 stainless steel for strength and long-term durability. Chrome-plated brass hex nuts and pre-installed washers allow a hand-tight, leak-resistant seal without special tools. Rated to 125 psi and 180 degrees F, this connector meets the demands of residential, commercial, and industrial plumbing installations. Licensed plumbers and skilled tradespeople install this connector as a standard toilet rough-in or replacement supply line.

This connector is sized at 1/2 inch FIP on the supply stop end and 7/8 inch ballcock (BC) nut on the toilet fill valve end, with an overall length of 20 inches. That length accommodates most standard toilet rough-in depths where the shutoff valve is located in the wall or floor below the tank. It is approved for water supply connections to plumbing fixtures in residential, commercial, and industrial settings. IAPMO listing confirms compliance with recognized plumbing codes and product standards.

Compatibility

Designed for water supply connections to toilet fixtures using a 1/2 inch FIP supply stop and a standard 7/8 inch BC nut ballcock or fill valve inlet. Suitable for residential, commercial, and industrial plumbing applications per IAPMO listing.

Installation Notes

Shut off the water supply at the angle stop or main shutoff and flush the toilet to relieve line pressure before removing the existing supply line. Thread the FIP end onto the supply stop and the BC nut end onto the fill valve inlet by hand, then snug with pliers — do not overtighten, as over-torquing brass nuts can crack the fill valve shank. After installation, slowly restore water pressure and inspect both connections for leaks. Installation must comply with applicable local plumbing codes and IPC requirements.
