These fittings are made to tighter tolerances than other stainless steel pipe fittings. They are also known as instrumentation fittings.

Also known as Code 61 SAE hydraulic flanges.

These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces.

Also known as Code 61 SAE hydraulic flanges.

When space in your pipe line is limited, choose these miniature fittings that are one inch or less in length.

Individually bagged to prevent contamination, these fittings are suitable for applications that require a high level of cleanliness.

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included.

Polished to at least a 15 Ra finish on the inside, these fittings have an ultra-smooth interior surface that helps prevent contamination. They are also known as ultra-high-purity fittings.

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.

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.

Made of brass, these fittings have good corrosion resistance.

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.

These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications.

Use these luer lock couplings to quickly connect low-pressure air and water lines. Made of stainless steel, they’re more durable than plastic couplings.

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 plastic, these couplings are lighter in weight than metal luer lock couplings. They're a popular choice in labs because of their versatility—they fit any other luer lock plug, socket, syringe, or needle.

These fittings include a nut with a built-in sleeve (ferrule), so there’s no need to remove the nut for assembly.

The nickel plating on these fittings provides better corrosion resistance than unplated brass fittings.

Aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

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

A staple in labs, these couplings are highly versatile, fitting any luer lock plug, socket, syringe, or needle. They’re PVDF, so they resist most acids, alcohols, and organic solvents.

Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push. An internal gripping ring holds the tubing tight.
