Brass Push Tube Fitting, 0.25 Inch Tube OD To 1/8 NPT Male, 90 deg Elbow

This brass fitting is designed for industrial fluid systems, offering a secure and efficient connection suitable for handling the pressures typically found in those applications.

For that kind of tight routing situation, a 90-degree push-to-connect elbow like this one is about as clean a solution as you'll find. The tube side accepts 0.25 inch OD tubing and the threaded end is 1/8 NPT male, so as long as your valve port is a 1/8 NPT female, you're connecting directly with no adapters in between. Push the tube in, thread the fitting into the port, and you've changed your flow direction without eating up extra space.
