PATIKIL RXZER23 Brass Pipe Fitting Reducers, 1/4" G Female to 5/16" Flare Male, 2-Pack

When a pipe connection needs to bridge a 1/4" G female fitting and a 5/16" flare connection, these PATIKIL brass reducers provide a direct way to join the two sizes. The set includes two fittings for air-conditioning, refrigeration and other compatible line work.

Each reducer has a hexagonal nut to help with tightening or loosening during installation. Its brass construction is intended for use in plumbing and fluid-line connections where a flared tube needs to meet a differently sized fitting.

For a practical installation, connect the male flare end to a correctly sized flared tube, then attach the female end to a matching male adapter. Check the tube’s outside diameter when selecting the flare size: the flare measurement refers to the tube size, not the fitting’s thread size.

Getting the most from it

These fittings are made for joining pipes or fittings of different sizes, rather than replacing a whole line or requiring both ends to use the same connection. For example, in an HVAC or refrigeration connection, the 5/16" male flare end can connect to a flared tube while the 1/4" G female end mates with a compatible male adapter. The included hex nut gives you a practical surface to grip when tightening or loosening the fitting.

The listed applications also include hydraulic and pneumatic systems, automotive connections, humidifiers, grills and fire pits. Use the pair with compatible flared copper, brass or aluminium tubing, and match the tube size and fitting connections before installation. For a sound connection, make sure the tube is properly flared and the mating adapter has the corresponding thread.

Benefits

A reducer is useful when the existing tube and the receiving fitting do not share the same size. Instead of choosing a connection that matches only one end, this format brings a 5/16" flare male connection and a 1/4" G female connection together in one fitting. That makes it a focused option for compatible HVAC, refrigeration, gas-line, hydraulic and pneumatic tasks where those two connection types are required.

The brass body is described as resistant to wear and corrosion, with a stated operating temperature range of -53℃ to 121℃. Standard, clearly formed threads are intended to support a secure connection, while the fittings also come with protective covers to help guard the threads from damage. The two-piece set is useful when working on a pair of connections or keeping a spare fitting available for a matching job.

Compared with sourcing separate fittings for each end, this reducer combines the size change and connection in a single component. Its value is in matching the specific tube and adapter already in the installation, so identify the flare tube’s outside diameter and the receiving adapter’s thread before fitting it.

Buying verdict

Choose the PATIKIL RXZER23 set for compatible pipework that needs a 5/16" flare male end to meet a 1/4" G male adapter. With two brass reducers, a hexagonal nut for handling and applications spanning HVAC, refrigeration and other listed systems, it offers a practical way to connect different-sized flared lines without changing the intended connection points.
