This post is a continuation from our blog "Common Fitting Types & Applications: Part I"

Some additional common types of fittings include:

SAE J1453 O-RING FACE SEAL FITTINGS: The metal-to-metal seals of flare and flareless fittings are the best choice for many applications, yet they are not as reliable as O-ring seal fittings when it comes to maximum sealing in many lower pressure applications. 

Each type of fitting connects to a tube, hose or a port.  A port connection is part of a component, such as a manifold or pump.  All fittings are made to industrial standards, the most common of which are:

The safety, reliability and service life of a system are only as good as its transfer lines and connections.  Tube fittings and adapters are critical components in tubing and hose connections, valves, hydraulic systems, pumps and cylinders.  The right connection of the fitting and tube or hose provides outstanding leak free service life, even at high temperatures, pressures, corrosive environments and steady vibration cycles.
