Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
Ultra-Corrosion-Resistant Yor-Lok Fittings for Nickel Alloy Tubing

- For Use With: Acetic Acid, Air, Bleach, Cutting Oil, Diesel Fuel, Formic Acid, Fuel Oil, Gasoline, Hydraulic Fluid, Iron Chlorides, Mineral Oil, Salt Water, Steam, Water
- Temperature Range: 0° to 1000° F
- Tubing: Use with seamless soft C276 nickel
- Specifications Met: ASME B31.3
With the best corrosion resistance of any metal tube fittings we offer, these C276 nickel Hastelloy fittings stand up to aggressive chemicals and resist pitting and cracking from stress. 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-resistant seal. Fittings are compatible with Swagelok®, Let-Lok, and A-Lok fittings.

Minimal-Spill Push-and-Turn Hose Couplings for Chemicals

Quickly connect and disconnect hose lines used with a variety of chemicals, from adhesives to isopropyl alcohol and ink. Any part of these couplings that contacts fluid is made from 316 stainless steel, C-276 Hastelloy, PTFE, or fluoroelastomer to withstand the chemicals in your line. Tough enough to handle frequent use, these couplings are designed to be virtually spill free. Also known as dry disconnects and double-shut off couplings, both the plug and the socket have a shut-off valve that stops the flow of liquids when they’re separated. To connect, push the plug into the socket and lock with a quarter turn. The socket swivels, so you won’t have to twist your hose to attach the plug. It also has a rubber lip and large handles to prevent damage if it’s dropped.
A complete coupling consists of a plug and a socket (both sold separately). They’re compatible with MannTek, Avery Hardoll, Todo-matic, and other dry-disconnect couplings that meet NATO standard STANAG 3756.
Aluminum couplings are lighter in weight than stainless steel and have good corrosion resistance.
316 stainless steel couplings have excellent corrosion resistance.

Ultra-Chemical-Resistant Threaded On/Off Valves

The most chemical-resistant threaded valves we offer, these have a PTFE seal and an alloy body that can withstand extremely aggressive and corrosive chemicals, such as methyl ethyl ketone and toluene. They are standard port, so they slightly restrict flow.
Monel valves are more corrosion resistant than Alloy 20 valves.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
- Valve Type: Ball
- For Use With: Acetone, Air, Carbon Dioxide, Diesel Fuel, Gasoline, Kerosene, Methyl Ethyl Ketone, Nitrogen, Salt Water, Soap Solutions, Sodium Hydroxide, Toluene, Water, Xylene
- Ball Material: Monel
