Our Copper Reducing couplings
- Manufactured in accordance with ASME B16.22, all of Lawton Tubes ACR fittings are seamless and one-piece, making them more durable and easier to use.
- We supply our ACR fittings in a wide variety of sizes, ranging from 3/16” to 4 1/8”.
- Furthermore, we also provide high-pressure fittings for CO2 applications, which are frequently required for large retail installations. For a swift delivery, we keep all fittings in stock.
- For added traceability, all Lawton Tube fittings are etched whenever it is practical. We supply a wide range of silver solder brazing alloys suited to various product types and applications.
Benefits of Our Couplings Include:
- We seal all our couplings in protected, product-labelled polythene bags.
- Fittings are supplied in reinforced cardboard boxes, labelled with product information and outline drawing of fitting.
- Each fitting is engraved with unique branding, space permitting
Copper Fittings for Co2
Degreased copper fittings specifically for ACR and manufactured to ASME B16.22-2001 which can be used in assemblies subject to the Pressure Equipment Directive.
The burst pressure of each fitting size at 55ºc has been determined and a safety factor of at least 3 has been applied to establish a recommended maximum working pressure.
All testing has been conducted in accordance with BS EN 378-2:2008 (+A1:2009).
