1/8" NPT Male to 1/4" Push-to-Connect 90° Vacuum / Boost Fitting
The JBtuned 1/8" NPT Male to 1/4" Push-to-Connect 90° Fitting converts a 1/8" NPT female port to a 1/4-inch push-to-connect interface while immediately turning the reference line 90 degrees.
This configuration is useful when the threaded component provides a 1/8" NPT female port but surrounding components leave limited room for a straight reference-line exit.

Threads Into a 1/8" NPT Female Port
The threaded side of this fitting is 1/8" NPT male and is designed to mate with a compatible 1/8" NPT female port.
NPT is a tapered pipe-thread connection and is different from an AN flare connection. Verify the port type on the component before ordering rather than selecting a fitting based only on approximate thread diameter.
Choose the 90° Version for Immediate Line Routing
Use the 90° configuration when the 1/4" reference line needs to turn immediately after leaving the threaded port.
If there is enough room for the line to continue directly away from the port, use the 1/8" NPT Male to 1/4" Push-to-Connect Straight Fitting.
Vacuum & Boost-Reference Applications
1/8" NPT ports are commonly encountered on aftermarket performance components and distribution hardware used in vacuum and boost-reference systems.
This fitting provides a compact transition from that threaded port to the JBtuned 1/4" push-to-connect plumbing system.
Reference-line routing should follow the requirements of the component being connected. Blow-off valves, wastegates, boost-control systems and other devices may require different pressure-source locations.
Need Two Push-to-Connect Branches?
If the 1/8" NPT port needs to supply two separate 1/4" push-to-connect reference lines, use the 1/8" NPT Male to Dual 1/4" Push-to-Connect Tee.
Questions About the Connection?
If you are unsure whether your component has a 1/8" NPT female port or a -4AN male connection, verify the port before ordering. JBtuned offers separate fittings for both connection families.
