Nuts & Tube Sleeves

The stainless steel nuts and tube sleeves we manufacture at Custom Fittings are recognised by leading companies in a range of sectors to be of the very highest quality. We supply 13 different products to meet your needs, with both BSP’P and JIC connections.

Our desire to innovate means that we invest in the latest best custom machinery and hire only the very best specialist engineers. Our customers in the nuclear, automotive, transportation and petrochemical industries share our passion for British manufacturing, which is why they choose our industrial fittings again and again.

We began trading as a small family business, but over the last 30 years Custom Fittings has grown to become one of Europe’s leading fitting manufacturers, with 75 employees and operating from our state-of-the-art manufacturing and warehousing facility in West Yorkshire. We’re proud to say that all of the 3,000+  products we now manufacture and stock meet our Quality Assurance Policy as detailed in our ISO 9001 certification. Our commitment to the family values that we started with remains: just call our friendly and knowledgeable customer service team and see for yourself!

We offer international shipping and export to over 50 countries worldwide. Watch the countdown on our website: we 100% guarantee same day despatch, with urgent orders for stock items despatched within the hour.

Our team of engineers use the most sophisticated machinery available: all of our nuts and tube sleeves are CNC lathe-turned and made from 316 Stainless Steel. Stainless steel offers the best value over a lifetime, because of its superior corrosion, fire and heat resistance, hygienic qualities and aesthetic appearance. We offer both off-the-shelf and bespoke products and carry high stock levels of raw materials, so all parts can be rapidly manufactured specifically for your needs out of other high nickel alloys.
