B38;K Llc 102-053HN Boiler Drain Ball Valve 1/2 Inch

Product Description

The B38;K LLC 102-053HN is a 1/2-inch boiler drain valve that uses a quarter-turn ball valve mechanism for fast, positive shutoff. The ball valve design eliminates the multi-turn operation of older hose bibb-style drains, allowing a technician to open or close the drain in a single 90-degree handle rotation. Measuring 2.77 inches in length, 1.76 inches wide, and 1.05 inches in height, this compact fitting is well suited for tight mechanical room installations. Weighing 0.32 pounds, it adds minimal load to the boiler connection. Plumbers and HVAC technicians install this valve when servicing or replacing system drain points on hot water heating equipment.

This boiler drain is used on residential and light commercial hot water heating systems where a reliable, low-profile drain port is needed at the boiler, radiation loop, or zone manifold. The quarter-turn ball valve operation is preferred in service work because it provides a clear open or closed indication and reduces the risk of a stuck or weeping stem that is common with traditional compression-style drain valves. It is sold individually and is appropriate for new installation or direct replacement of an existing boiler drain fitting on a 1/2-inch connection.

Installation Notes

Installation is performed by a licensed plumber or HVAC technician. Shut down the boiler and relieve system pressure before removing the existing drain valve. Apply thread sealant tape or compound to male threads per local plumbing code requirements, referencing IPC guidelines where applicable. Do not overtighten the fitting into cast iron or aluminum boiler tappings, as thread damage can cause persistent leaks.
