kfa² ball valve 1" female-female water fitting, model 700-120-25

kfa² ball valve 1" female-female water fitting, model 700-120-25 is a compact 1-inch female-to-female ball valve designed for straightforward on/off control of water flow in domestic and light commercial plumbing systems. The valve provides reliable shut-off performance for threaded water lines and is suitable for inline installation where two female-threaded fittings must be joined or replaced. Its simple design enables easy integration into supply lines, manifolds and repair applications.

Advantages

The ball valve offers a compact form factor and a full-bore design that allows efficient water passage with minimal pressure loss. Threaded female-to-female connections simplify replacement of existing fittings without additional adapters. The valve's straightforward quarter-turn operation provides rapid shut-off and clear open/closed indication, while the metal construction ensures mechanical durability for typical domestic and commercial water systems.

Suitable for

• Inline shut-off of cold and hot water supply lines
• Replacement of worn or leaking female-threaded fittings
• Integration into manifolds, distribution headers and service branches
• Plumbing repair and maintenance in residential and small commercial installations

Key specifications

• Connection type: 1" female threaded on both ends
• Valve type: quarter-turn ball valve for on/off control
• Application medium: potable water and general water supply systems
• Installation position: inline, suitable for horizontal or vertical pipe runs
• Operation: manual handle (quarter-turn)
• Material: metal body and internal ball components suitable for standard plumbing use

How to use

Shut off the upstream water supply before installing the valve. Thread the female ends onto male-threaded pipe or fittings using an appropriate sealant or tape on the male threads to ensure a watertight connection. Tighten by hand and finish with a wrench if required, taking care not to over-torque. Operate the valve using the handle: a 90-degree turn closes or opens the flow. Inspect for leaks after re-pressurising the line and adjust connections if necessary.

Usage recommendations

For long-term performance, avoid excessive torque during installation and cycle the valve periodically to prevent sticking. Use the valve in water systems within typical domestic pressure ranges and follow local plumbing codes when replacing or integrating fittings into supply systems.
