Sanitary Spool Tube with 1.5 in Tri Clamp - 24 in Stainless Steel

In this review the DERNORD sanitary spool tube is evaluated for shop and process use where sanitary flow and corrosion resistance matter. The bottom line: this 24 in seamless stainless steel tube with 1.5 in tri-clamp ferrules is best for anyone needing a short, sanitary connection that resists chloride environments and delivers smooth interior flow. Its polished interior and seamless construction are the single biggest reason to buy when cleanliness, burst strength and an exact ferrule OD of 50.5MM are required.

Key Features

• Seamless construction: Provides a smoother interior for reduced fluid hang-up and higher burst strength compared with welded tubing.
• Stainless Steel 304: Offers reliable corrosion resistance suitable for many food, beverage and chemical service applications.
• Polished inside and out: Internal and external polishing improves cleanability and helps meet sanitary requirements.
• Tri-clamp ready: Ferrule OD 50.5MM and 1.5 in tri-clamp fitment make it easy to integrate with standard sanitary fittings.
• Annealed for formability: Restored ductility allows bending or flaring when custom routing or fitting adjustments are needed.
• Compact 24 in length: A 610mm tube length suits inline spool connections where space is limited or short runs are preferred.

Who It's For

This spool tube is aimed at tradespeople, small processors and hobbyists building sanitary lines in food and beverage, brewing, or laboratory setups who need a reliable 1.5 in tri-clamp connection with a polished, seamless bore. It is also useful for HVAC and plumbing situations where corrosion resistance and a smooth interior are priorities.

Those who should look elsewhere include users needing longer continuous runs or larger diameters, and installations that require specialty alloys beyond SS 304 for extreme chloride or high-temperature service.

Pros & Cons

Pros

• High-quality finish and seamless build deliver smooth flow and easy cleaning.
• Correct ferrule dimensions (50.5MM) and 1.5 in tri-clamp compatibility simplify installation with common sanitary fittings.
• Stainless Steel 304 offers broad corrosion resistance for many industrial and food applications.
• Annealed tube can be bent or flared for custom fitment without cracking.

Cons

• Length is fixed at 24 in so multiple spools or custom lengths are needed for long runs.
• SS 304 may not be sufficient for very aggressive chloride or high-temperature environments where duplex or 316L would be preferred.

Frequently Asked Questions

Is this tube compatible with standard 1.5 in tri-clamps?
Yes, the ferrule OD of 50.5MM is specified for a 1.5 in tri-clamp connection and is intended to mate with standard sanitary clamps and gaskets.

Can the tube be bent or flared for custom installations?
Yes, the tube is annealed to restore formability so it can be bent or flared as needed for routing, within normal limits for 304 stainless.

Is this material suitable for food and beverage service?
Yes, the seamless SS 304 construction with internal polishing is intended for sanitary purposes and common food and beverage applications.
