The MIDLAND INDUSTRIES 923220 is a lead-free supply connector designed for toilet fill valve (ballcock) installations in residential and light commercial plumbing. It connects a 3/8-inch compression shutoff valve to a 7/8-inch ballcock inlet, spanning 20 inches in length. The braided stainless steel outer jacket resists corrosion and handles the mechanical stress of routing in tight cabinet or wall spaces. Heavy-duty brass inserts at each end provide secure, leak-resistant seat contact and resist deformation during tightening. At 0.24 pounds, this connector is lightweight and easy to handle during installation.
This connector fits standard toilet tank ballcock inlets where a 3/8-inch compression supply stop is present. The 20-inch length accommodates common rough-in configurations where the shutoff valve is offset from the tank inlet. It is suited for residential bathroom and commercial restroom applications. Licensed plumbers and experienced DIYers installing or replacing toilet supply lines will find this connector a direct drop-in solution for ballcock-style fill valves.
Designed as an OEM-style replacement supply connector for standard residential and commercial toilet installations equipped with a 3/8-inch compression shutoff and a 7/8-inch ballcock inlet.
Installation is typically performed by a licensed plumber or a qualified tradesperson familiar with IPC and local plumbing codes. Shut off the water supply at the angle stop valve and flush the toilet to relieve line pressure before disconnecting the existing supply line. Hand-tighten the compression fitting first, then snug with an adjustable wrench - do not overtorque, as excessive force can crack the ballcock shank or deform the compression ferrule. Inspect both connection points for drips after restoring water supply and confirm the fill valve cycles correctly before closing the service call.
