How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Medium-Pressure Aluminum Threaded Pipe Fittings
Designed for medium-pressure applications, these fittings have better strength than our low-pressure aluminum pipe fittings. They are lightweight with good corrosion resistance.
Fittings with blue anodized finish have better corrosion resistance and a harder surface than plain aluminum fittings.
Miniature Medium-Pressure Aluminum Threaded Pipe Fittings
Their small size makes these miniature fittings a good choice for cramped, confined spaces. They are designed to handle medium-pressure applications. Fittings are aluminum, which is lightweight with good corrosion resistance.
Metric and UN/UNF (SAE Straight) male threads have a gasket to protect against leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.

Easy-Fit Barbed Hose Fittings for Air and Water
Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into rubber hose and secure with a clamp.
Aluminum fittings are lighter in weight than other metal fittings. They have good corrosion resistance. Fittings with a threaded end are also known as hose nipples.
Fittings with a hex body can be tightened with a wrench.
