Compression Tube Fittings for Food and Beverage
- Temperature Range: -40° to 200° F
- Tubing: Use with firm or hard (Durometer 45D-65D) EVA plastic, nylon plastic, polyethylene plastic, polypropylene plastic, or polyurethane rubber
- Specifications Met: NSF/ANSI 51
A single sleeve (ferrule) and a gripping ring compress the tubing as you tighten the nut, creating a strong seal. The nut, sleeve, and gripping ring are included. Fittings are also known as flareless fittings. They are nylon for excellent impact and abrasion resistance.
NPTF (Dryseal) threads are compatible with NPT threads.

High-Temperature Compression Tube Fittings for Food and Beverage
- Temperature Range:
Inch: -40° to 270° F
Metric: 0° to 240° F - Tubing: Use with firm or hard (Durometer 45D-65D) nylon plastic, polyethylene plastic, or polypropylene plastic
- Specifications Met:

Metric: FDA Compliant 21 CFR 177.2510, NSF/ANSI 61
Made of PVDF (also known as Kynar), these fittings have excellent strength and can handle temperatures as high as 240° F or 270° F. All fittings meet NSF/ANSI 61 and are safe to use for drinking water systems. They’re also known as flareless fittings.
Assemble fittings with a plastic sleeve without removing their nut. This built-in sleeve—commonly called a ferrule—compresses the tubing as you tighten the nut, creating a strong seal.
Fittings with a silicone O-ring create a strong seal for male BSPP threaded connections and resist high temperatures.

Tube supports are recommended if you want to use fittings with soft nylon, polyethylene, and polypropylene tubing to prevent the tube from collapsing.
Nuts with Built-In Sleeve for High-Temperature
Compression Tube Fittings for Food and Beverage
- Temperature Range: -40° to 270° F
- Tubing: Use with firm or hard (Durometer 45D-65D) nylon plastic, polyethylene plastic, or polypropylene plastic
- Specifications Met: FDA Compliant 21 CFR 177.2510, NSF/ANSI 51, NSF/ANSI 61, USP Class VI
Use these nuts with high-temperature compression fittings for food and beverage to create a seal on plastic tubing. They have a built-in sleeve (ferrule), so the sleeve is positioned correctly for installation. Thread the nut onto the fitting, then insert the tubing and tighten the nut. Nuts are PVDF (also known as Kynar), which has excellent strength and can handle high temperatures up to 270° F.

Sanitary Compression Tube Fittings for Food and Beverage
- Temperature Range: 25° to 300° F
- Tubing: Use with firm or hard (Durometer 55D-65D) FEP plastic, nylon plastic, or PTFE plastic
- Specifications Met: EHEDG Certified, FDA Compliant 21 CFR 177.2600
Connect tubing in sanitary food processing areas with frequent washdowns. Certified by EHEDG (European Hygienic Engineering and Design Group) to meet sanitary design standards, these fittings have a smooth, polished surface with no pits or crevices where bacteria could grow. All edges are rounded and there are no horizontal ledges, so liquids drain and debris is easy to wash off. Rated IP69K, these fittings can handle the high pressures and temperatures of washdowns common in sanitary cleaning protocols. Made of stainless steel, they won’t corrode from water or harsh cleaners.
The seals on these fittings keep out water and contaminants. They also prevent metal-to-metal contact, which can create small gaps that trap bacteria. FDA compliant, the seals are safe for contact with food. Since they’re bright blue, they’re easy to spot if they fall off into your line.
These fittings have a single sleeve (ferrule) that bites into plastic tubing to make a seal—no heating, flaring, or soldering tools required. They’re also known as flareless fittings. Since they’re threaded, you can take apart their connections as needed for maintenance and repair.
