## Description

This Anderson Metals half union compression tube fitting is made of brass, has a flared tube connection and a male NPT connection, and is suitable for use with fuel and gas systems. It is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. This fitting can be used with copper, brass, aluminum, or steel tubing to connect and disconnect two tubes more easily than with a coupling. It has a flared tube connection on one end and a male National Pipe Taper (NPT) connection on the other for connecting to a female NPT threaded tube, creating a tighter seal than straight threads. This fitting is part of an assembly that resists mechanical pullout for a more secure connection, and can be assembled and reassembled without affecting the seal. This half union compression tube fitting has an operating temperature range of -65 to +250 degrees F and is suitable for use with fuel and gas systems, plumbing, refrigeration, and vacuum applications.Tube fittings are components used for connecting, branching, terminating, and changing the direction of tubing in pneumatic and hydraulic systems. They are made of brass, stainless steel, PBT (polybutylene terephthalate), and other materials that resist corrosion and wear. Tube fittings have various types of connections, including threaded, welded, barbed, and push-to-connect (also called one-touch). Push-to-connect connections do not require tools or sealants. Tube fittings are used in various applications, including machine tools, airplane and truck controls, and automated production lines, among others.Anderson Metals manufactures brass fittings, valves, and pipe nipples. The company, founded in 1951, is headquartered in Kansas City, MO.

Review: Solid, High-Quality Brass Fitting – Perfect for Gas and Propane Lines - I recently picked up the Anderson Metals 54048-0606 Brass Half-Union for a home project involving a gas line, and I am very impressed with the quality. Finding reliable fittings is critical for safety, and this one definitely delivers. Why I recommend it: Precision Machining: The threads on both the 3/8" Flare and 3/8" Male NPT sides are incredibly clean and smooth. I had no issues with cross-threading, and they provided a very tight, secure seal without any leaks. Heavy-Duty Construction: It’s made from solid, high-quality brass, which gives it great corrosion resistance and durability. You can feel the weight and quality compared to cheaper, generic alternatives. Reliable Seal: This fitting is designed to resist mechanical pullout, making it ideal for systems that might experience vibrations or high pressure, like propane grills or HVAC setups. Ease of Use: The half-union design makes it much easier to connect and disconnect tubing than a standard coupling, which is a huge time-saver for maintenance. Things to Note: Not for Potable Water: As with many brass fittings of this type, it is not rated for drinking water use in the U.S. due to lead content laws. Confirm Your Sizes: Make sure you need the 3/8" Flare to 3/8" Male Pipe specifically, as "pipe size" (NPT) is a nominal measurement and not the actual outer diameter of the thread. Overall, if you need a dependable, leak-proof brass fitting for fuel, gas, or refrigeration lines, Anderson Metals is a trusted brand for a reason. Great value for the price!
Review: Fit my HVAC vacuum pump perfectly. - Fit perfectly on my MasterCool Vacuum pump. I was looking to improve my vacuum times, I recently purchased a Yellow Jacket vacuum pump tree that had a 1/2" connection. The original connection was 5/16" and 1/4", which wouldn't work. This connection worked flawlessly, I tested it last night on a 30lb recovery bottle. I was able to pull down to 500 microns in 6min,27sec, which is amazingly fast. Using a set of Fieldpiece SMAN manifold typical time is about 20-30 minutes. The brass fitting was perfect, no burs or blemishes. The treads were true and I was able to securely connect a my hoses to it. Superb quality, zero issues at a decent price. Thanks!
