Infinity Stem Reducer

Infinity Stem Reducer (Reducing Bushing)

The Compact “Plug-In” Solution for Pipe Reduction

Customize your air piping layout instantly with the Infinity Stem Reducer. Often referred to as a “plug-in reducer” or “reducing bushing,” this clever component features a smooth stem (spigot) on one side and a push-to-connect socket on the other.

Designed to eliminate the need for bulky couplings or short “jumper” pipes, the Stem Reducer plugs directly inside a standard Infinity fitting (like a Tee or Elbow), instantly converting that port to receive a smaller diameter pipe. It is the most efficient way to step down line sizes for drops, branch lines, or manifold assemblies.

Key Features & Benefits

• Instant Fitting Conversion:

Transform a standard 50mm Tee into a 50mm-to-32mm reducing tee in seconds. Simply push the stem end into the fitting, and it locks in place just like a piece of pipe.

• Zero-Space Reduction: Because the reduction happens inside the fitting, there is no added length to your pipe run. This allows for extremely tight, professional-looking installations, especially when running drops down columns or walls.
• Cost-Effective Versatility: Instead of stocking expensive, specialized reducing tees for every possible size combination, you can stock standard Equal Tees and a handful of Stem Reducers. This modular approach simplifies inventory and lowers project costs.
• Leak-Free “Push-to-Connect”:
  • Stem Side: Engages with the grab ring of the host fitting.
  • Socket Side: Features the patented Infinity internal grip system to lock the smaller pipe securely.
• Full-Flow Efficiency: Engineered with a smooth internal taper that funnels air from the larger diameter to the smaller one without the turbulence or pressure drop associated with threaded bushings.

Technical Specifications

• Configuration: Male Stem (Spigot) x Female Push-to-Connect Socket
• Material: Nickel-Plated Brass or Technopolymer (depending on size)
• Pressure Rating: Up to 232 PSI (16 Bar)
• Temperature Range: -4°F to +176°F (-20°C to +80°C)
• Size Format: Stem OD (Outer Diameter) x Tube OD (Outer Diameter)
  • Example: A 50mm x 32mm Stem Reducer fits into a 50mm fitting and accepts a 32mm pipe.

Ideal Applications

• Manifolds: Inserting reducers into the outlets of a tee to create multiple small distribution lines from a single header.
• Drops: Stepping down from a ceiling main (e.g., 40mm) to a workstation drop (e.g., 25mm) directly at the elbow.
• Machine Connections: Reducing the line size right at the equipment connection point to match the inlet port.
