Approved Press Tools
Lawton 316L Gas Press Fittings are approved for use with M-profile pressing systems from:
- Novopress
- Geberit
- Rothenberger
- REMS
Important: Matching press tools, adaptors, jaws and slings from the same manufacturer must always be used during installation.
Material Compatibility
Dissimilar Metals
Installations containing mixed metals should generally be avoided, as galvanic corrosion may occur when dissimilar metals are connected directly together.
Where mixed-metal systems are unavoidable:
- Follow Gas Safety (Installation and Use) Regulations 1998.
- Apply recognised good engineering practice.
- Consider appropriate isolation measures where necessary.
Grade Compatibility
- 304 and 316L stainless steel tubes and fittings can be used within the same system.
- Overall corrosion resistance will be determined by the least corrosion-resistant component used.
Key Benefits
- Designed specifically for fuel gas installations
- Heat-free, flame-free installation
- Fire-tested HTC performance
- Suitable for compressed air systems
- Compatible with EN 10312 stainless steel tube
- Wide size range from 15mm to 108mm
- Fully compatible with approved M-profile tooling
- Backed by a 50-year warranty
General
Conex Bänninger >B<MaxiPro fittings must be installed by an installer who is appropriately trained and qualified to work on air conditioning and refrigeration installations and certified via the >B< MaxiPro training course. All installations must be completed in line with local regulations and by-laws governing the installation, and all applicable health and safety practices must be adhered to. When using the press tools, care must be taken to ensure hands are kept away from the jaw during the pressing process. Always wear ear and eye protection.
Important
Select the correct size of tube, fitting and jaw for the job. Ensure the fitting and tube are kept free of any dust or dirt and that the O-ring is undamaged. Check the inner pressing contour of the jaw is free of dirt and debris. Do not force tube ends together prior to making joints. Joints should only be made on an unstressed pipework assembly.
Remarks
- A joint is finished after one complete compression cycle of the tool.
- Do not press any >B< MaxiPro fitting more than once.
- Pipework alignment must be completed prior to pressing.
- Do not rotate joints after they have been pressed.
