Tubing for Liquids | McMaster-Carr

Made from TPE plastic, this tubing doesn’t contain plasticizers like DEHP, so it won’t impart tastes or odors to the fluid passing through. The surface isn’t absorbent, making it easy to clean. Tubing is clear, so you can monitor flow.

Tubing with a PVDF liner is often used in pharmaceutical applications since it won’t bind to proteins or leach substances into the fluid moving through. It’s more flexible than tubing made entirely from PVDF.

Tygon tubing resists staining and won’t break down when exposed to alcohol and acids. It’s often used with wine, coffee, and other pigmented liquids.

High-Purity Hard Plastic Tubing

Semi-Flexible
Compatible with Compression Tube Fittings
Hard (Durometer 60D)
Temperature Range: -320° to 500° F

With hard walls and the ability to handle extreme temperatures, this PFA tubing is the preferred material for semiconductor applications. The material contains extremely low levels of additives, so it won’t contaminate the fluid passing through it. Tubing meets USP Class VI specifications for material testing; it is not for use in medical applications. It meets UL 94 V-0 for flame retardance, so it delays the spread of flames to valuable equipment. Tubing is clear, so you can easily monitor flow through the line. It is semi-flexible, so it is good for gradual bends.

Abrasion-Resistant Duct Hose for Liquids

Flexible
Color: Black or Gray
Temperature Range: -40° to 300° F

If your liquid contains some solid particles, this tough EPDM rubber hose can handle the extra abrasion. Hose is for use with water and noncorrosive acids.

Transfer material from sifters, feeders, and strainers to other parts of your sanitary line with these hose lengths and fittings. They’re 3-A and USDA certified to meet sanitary design standards, as well as FDA compliant for direct contact with food. Cuffs at each end of the hose have grooves that snap into matching grooves on fittings. These grooves form a seal that’s more sanitary than hose clamp connections, since there are no gaps where contaminants could gather. It’s also tighter and less likely to leak than hose clamps. When pressure increases, the hose presses against fittings, tightening the seal. You don’t need tools to install or remove this hose—squeeze the end cuff to slide it into or out of fittings.

Made from flexible, abrasion-resistant plastic, this hose won’t crack and rip from the movement of your machines. It’s also chemical-resistant, so it holds up to frequent washing during clean-in-place (CIP) cycles. The smooth seams won't trap food and other particles. It's clear, so you can monitor flow.

When choosing a hose length, consider the side-to-side, horizontal, and rotational movement of your machines. You’ll need hose that’s slightly longer than the gap between equipment to account for movement and vibration.

Hose with 1" coil is good for applications with up-and-down movement, such as bag feeders. The closely-spaced internal coil helps the hose maintain its shape while it’s compressed.

Hose without coil has thick, flexible walls that bend side-to-side to handle misalignment and rotation. It’s often used with sifters and strainers. This hose doesn’t handle up-and-down movement as well as hose with 1" coil, since the walls may crease when the hose is compressed. Creases in the hose wall restrict flow, increase wear, and create pockets that trap food and liquids. This hose is latex-free and doesn’t include Bisphenol A (BPA), which is a chemical that can contaminate your line.

Fittings are stainless steel, which won’t corrode from harsh cleaners and sanitizers. You can cut them to fit onto existing pipes. Weld them to the inlets and outlets on your equipment before attaching hose.
