Press-Fit Tube Fittings
A great alternative to other tube fitting options, the sockets of press-fit tube fittings tightly grip tube ends with internal metal spurs. O-rings inside the fittings provide leak-proof seals in tube connections. Economical, easy to install, and versatile, press-fit tube fittings do not require glue, welding, or soldering to join tubes. While copper pipe press fittings are one popular version, press-fit tube fittings are also available in brass, carbon steel, and stainless steel, making them useful in a variety of applications, including chemical lines, gas lines, graywater or potable water lines, hydronic heating and cooling systems, and lines for oil, lubricant, or fuel. These fittings also vary by dimension, maximum pressure, and temperature range. Another tube fitting option to consider is a push-to-connect tube fitting.
