A nut with two sleeves (ferrules) gives these fittings extra gripping power. The sleeves bite into tubing as you tighten the nut, creating a strong seal.

No sleeve is required to assemble these fittings, which makes for a faster, more convenient installation compared to 37° flared fittings. They are also known as refrigeration and SAE fittings.

Connect air brake lines with fittings that won’t crack in sub-zero temperatures. They meet Department of Transportation FMVSS 571 safety standards, so they’re often used in commercial trucks and trailers.

A single sleeve (ferrule) compresses the tubing as you tighten the nut on these fittings, creating a strong seal. They are brass for good corrosion resistance.

Lighter in weight than their metal counterparts, these quick-disconnect couplings are made of acetal plastic. They are moisture resistant, so they won’t absorb water and lose strength, even in high-humidity environments.

With no latch, these couplings have a compact design to fit in small spaces. They can handle pressures up to 700 psi.

Not only are these chrome-plated brass couplings corrosion resistant, they’re also durable enough to handle pressures up to 250 psi and can be used with vacuum.

Made of brass, these fittings resist corrosion from water and are more durable than plastic and aluminum fittings.

Extreme pressures are no problem for these heavy-duty brass fittings.

Used in low-pressure pipe lines, these brass fittings have a plating that makes them shiny and improves corrosion resistance.

The male threads on these brass fittings have a sealant applied for extra protection against leaks. Also known as Pressure Class 125 fittings, they are built for use in low-pressure applications.

Not only do these brass fittings have the strength to handle high-pressure applications, the male threads have a sealant applied for extra protection against leaks.

Use these heavy-duty brass fittings for high-pressure drinking water applications.

When you're unsure of the exact thread type you need, these fittings have universal threads that are compatible with the most common ones (NPT, NPTF, BSPP, BSPT).

Also known as Silbraze fittings.
