About Measuring Fittings

Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Compression Fittings for Plastic Tubing—Chemicals

For Use With: PFA Plastic: Hydrochloric Acid, Sulfuric Acid
PTFE Plastic: Alcohol, Ammonia, Benzoic Acid, Bleach, Bromine, Coolant, Fluoboric Acid, Hydrochloric Acid, Hydrofluoric Acid, Nitric Acid, Organic Solvents, Sodium Carbonate, Sulfuric Acid
Temperature Range: PFA Plastic: 0° to 350° F
PTFE Plastic: -40° to 185° F
Tubing: PFA Plastic: Use with hard (Durometer 50D-65D) PFA or PTFE plastic
PTFE Plastic: Use with hard (Durometer 60D) PFA or PTFE plastic

A sleeve (ferrule) compresses the tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. Fittings are also known as flareless fittings. Fittings that include a gripper sleeve on the tubing create an even tighter seal.

PTFE fittings are highly resistant to most acids, alcohols, detergents, and solvents. They’re made by machining. Their nut is made of PVDF, which is resistant to halogens such as chlorine and bromine, strong acids such as hydrofluoric and nitric acids, and organic solvents.

Acid-Resistant Yor-Lok Fittings for Nickel Alloy Tubing

For Use With: Air, Cutting Oil, Diesel Fuel, Fuel Oil, Gasoline, Hydraulic Fluid, Hydrofluoric Acid, Mineral Oil, Salt Water, Steam, Sulfuric Acid, Water
Temperature Range: -325° to 900° F
Tubing: Use with seamless soft 400 nickel
Specifications Met: See table

Made of 400 nickel, these Monel fittings have the corrosion resistance to handle hydrofluoric and sulfuric acid. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They include a nut with two sleeves (ferrules). The sleeves bite into tubing as you tighten the nut, creating a strong, leak-tight seal. They are compatible with Swagelok®, Let-Lok, and A-Lok fittings.
