A major UK food and beverage manufacturer approached us at Pipeline Products after experiencing quality control and leakage issues in their stainless steel processing lines. Their existing pipeline fittings were difficult to clean and causing unnecessary downtime.

They required a hygienic connection system that was:

• Fully compliant with BS4825
• Compatible with stainless steel hygienic tube
• Easy to clean and reassemble

After a full system review, they chose to upgrade the entire line to RJT unions, the UK’s most widely used hygienic connection for food, dairy, brewing, cosmetics, and even AI cooling systems.

What are RJT fittings & why were they selected?

RJT (Ring Joint Type) fittings are a British‑standard hygienic union system designed for quick assembly and disassembly. An RJT union consists of:

• A hexagonal RJT nut
• A weld male
• A weld, pressed or machined liner
• A hygienic seal (NBR, EPDM, Viton, Silicone, PTFE, or EPDM Metal Detectable)

All wetted components are manufactured from 316 stainless steel, making RJT pipe fittings ideal for hygienic applications.

The solution: A complete RJT pipeline upgrade

At Pipeline Products, we supply a full range of RJT fittings, including:

• Complete RJT unions
• RJT weld males
• RJT weld liners and machined liners
• RJT hex nuts
• RJT seals (including metal detectable options)
• RJT spanners for assembly
• RJT blanks nuts, liners and males
• RJT bends, tees, reducing cones, and expand unions

All items were available from stock, ensuring minimal downtime during installation.

This upgrade created a fully compatible pipeline system built around RJT pipe fittings, improving hygiene and reliability across the entire production line.
