VIAIR 92855 Multiport T Fitting

The VIAIR 92855 is a brass multiport T fitting designed for mobile pneumatic systems. It provides one 1/4-inch male port, two 1/4-inch female ports and one 1/8-inch female port for branching air lines. This accessory suits 12-volt and 24-volt automotive installations where multiple connections are required from a single source. Builders who need more than three branch points will require additional fittings.

Connection capacity and layout

The fitting accepts a 1/4-inch male supply and distributes air through two 1/4-inch female outlets and one smaller 1/8-inch female outlet. It comfortably handles typical compressor duty cycles in on-board air systems. The 1/8-inch port limits flow for high-volume tools, so it is best reserved for pressure switches or gauges rather than primary actuators.

Thermals noise and power draw

As a passive brass component, the fitting generates no heat, noise or electrical draw during operation. It simply routes compressed air without affecting system thermals. Performance depends entirely on the compressor and tubing used upstream. No power supply or cooling consideration applies to this part.

Questions about this item

Will the 1/4 male thread on the VIAIR 92855 connect directly to my existing 1/4 NPT compressor port?

The 1/4 male thread is designed to screw into a standard 1/4 NPT female port found on many VIAIR compressors and air tanks, so it should mate with your existing hardware.

How can I verify the 92855 fitting is sealing properly after I install it?

Pressurise the system to its normal working pressure and apply soapy water to every joint; bubbles indicate a leak that needs tightening or fresh thread sealant.

Does the VIAIR 92855 package include thread sealant or extra plugs for the unused ports?

The box contains only the multiport T fitting itself; thread sealant and any 1/4 or 1/8 NPT plugs for unused ports must be purchased separately.
