UV-Resistant Hard Plastic Tubing for Chemicals
Ultraviolet light won’t cause this tubing to degrade or deteriorate.
TPE tubing was originally developed for transferring inks that react to UV light in digital and 3D printing. It blocks UV light to protect fluid running through the tube. It’s also compatible with a variety of solvents commonly used in ink transfer applications.
Opaque tubing does not allow you to see inside the line.
Semi-flexible tubing is good for gradual bends.

High-Purity Soft Plastic and Rubber Tubing
Designed for high-purity processes, this tubing is made without plasticizers like DEHP that can contaminate the fluid passing through it. It meets USP Class VI specifications for material testing; it is not for use in medical applications. Tubing is clear or semi-clear, so you can monitor flow. It’s also flexible and easily bends around objects.
Tubing with braid reinforcement has extra strength to handle higher pressures than nonreinforced tubing.

Cleaned and Bagged Metal Barbed Hose Fittings for Chemicals
Each of these metal fittings is double bagged to prevent contamination in areas that require a high level of cleanliness. They’re even clean enough to be used for oxygen service. Constructed from 316 stainless steel, they won’t corrode from repeat cleanings with harsh chemicals. They’re also called hose nipples. To connect them, slide the barbed end into plastic or rubber hose and secure it with a clamp.

International Standard ISO Minimal-Spill
Quick-Disconnect Hose Couplings for Chemicals
To minimize fluid loss when connecting and disconnecting your line, these couplings have flat faces for a close fit and shut-off valves to stop the flow—they meet ISO 16028, which is an international standard for hose couplings. They’re also known as flush-face and double shut-off couplings. A complete coupling consists of a plug and socket (both sold separately). They connect and disconnect quickly, so use them if you need to access a line frequently. Made of 316 stainless steel, they have excellent corrosion resistance and withstand a variety of chemicals.
Plugs are also known as nipples.
Sockets are push-to-connect style. To connect, push the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug ejects. These sockets have an internal fluoroelastomer gasket that resists a wide range of chemicals, including benzene, butyl alcohol, and ethylene glycol.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size. Pressure ratings are given for static (constant) pressure conditions.
Warning: Never attempt to connect or disconnect couplings when operating at maximum pressure. Stop the flow before you disconnect the line.

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.
