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.

Compact Extreme-Pressure Steel Threaded Pipe Fittings
These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces. They are galvanized and zinc-plated steel, which have better corrosion resistance than plain steel fittings.
NPTF (Dryseal) threads are compatible with NPT threads. BSPP and metric male threads have either a gasket, or a gasket and washer, to prevent leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads; the male threads have either a gasket or a gasket and washer to prevent leaks.

Compact Precision Extreme-Pressure Steel Threaded Pipe Fittings
Made to tighter tolerances than other steel pipe fittings, these are also known as instrumentation fittings. They are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces. They are galvanized steel, which has fair corrosion resistance.

Crimp these fittings onto steel pipe to form a tightly sealed connection that’s faster than threading or welding and doesn’t require heat. An internal gripping ring and rubber O-ring create a secure seal when crimped. They are designed to leak if fittings have not been crimped; a colored dot marks the leak path so it's easy to spot unsealed connections. These steel fittings are coated in zinc-nickel to resist corrosion, but will rust if frequently exposed to saltwater or harsh chemicals. They are comparable to Viega MegaPress steel fittings.
Fittings meet ASME B31 code requirements for use in pressure piping systems.
Fittings with an EPDM rubber O-ring are often used for water processing lines, fire sprinklers, and heating and cooling systems. EPDM rubber won’t degrade when exposed to water, ethylene glycol, and propylene glycol. These fittings meet UL 213 and FM 1920 standards for use in fire protection systems.
Buna-N rubber O-rings hold up to natural gas, propane, diesel fuel, lubricants, and other oils. Fittings with these O-rings are often used in fuel gas systems and air lines. They meet the ANSI LC4/CSA 6.32 standard for fuel gas systems and comply with the International Fuel Gas Code.
Unions separate into three pieces. Unscrew and remove the center nut for quick access to a line.

Crimping Tools
Crimping Tool
Crimping tools seal fittings in less than five seconds. These tools are cordless, so you can take them to any job. Connect the jaw or ring that matches your pipe size to these tools, then pull the trigger to crimp the fitting. The pivoting head lets you access connections from any angle.

Jaw and Ring Sets
Jaw and Ring Set
Jaw and ring sets include three jaws, three rings, and one ring actuator jaw. Jaws are for pipe sizes 1/2 to 1; they fit directly into the crimping tool. Rings are for pipe sizes 1 1/4 to 2; clip the ring around the fitting and use the ring actuator jaw and crimping tool to press the open ends together.

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.
Steel fittings are stronger and more durable than other metal fittings. They should be used in noncorrosive environments. Zinc-plated steel fittings have slightly better corrosion resistance than unplated steel fittings. Fittings with a threaded end are also known as hose nipples.
Fittings with a hex body can be tightened with a wrench.
