Stainless press fittings are designed to provide a tight fit when pushed together to allow the rough-in to be completed prior to pressing. This ensures you have the right design and tube placement and allows you to make adjustments, if required, prior to pressing. This is especially beneficial for vertical installations.Stainless standard fittings, with EPDM O-rings,
also feature a built-in leak path so they visibly leak prior
to pressing, making the process of checking all joints are
pressed and sealed more efficient.
Stainless tube is 316L grade (EN 1.4404) complying with DIN EN 10088, fabricated according to DIN EN 10312 and DVGW – W 541 and is supplied as straight 6m lengths with outside diameters in the range 15mm – 108mm. It is compliant with AS 5200.053 and has Watermark Approval #23151. Sanqing Stainless tubes combine low carbon, at less than 0.03%, with a minimum molybdenum content of 2.3% for improved corrosion resistance.
Low carbon, austenitic stainless steel is roll formed and then longitudinally plasma-inert gas-welded to precisely form the tubes.
Stainless fittings are manufactured and quality controlled to AS3688, with 316L (material EN1.4404) for parts made from tube, 316Ti (material EN1.4571) for threaded fittings and 316 (material 1.4408) for precision cast fittings
Features of Stainless press fittings
Fast and Easy to use
• Considerably faster than traditional jointing methods
• No need to drain water out of the system
• No waiting for adhesives to set
Safe, Heat-free, Flame-free connections
• No hot works permit required
• Ideal for retrofit projects
Stainless fittings are manufactured and quality controlled to AS3688, with 316L (material EN1.4404) for parts made from tube, 316Ti (material EN1.4571) for threaded fittings and 316 (material 1.4408) for precision cast fittings, all having Watermark Approval # 23087 for Standard (EPDM) and Industry (FKM) fittings.
Sanqing press fittings are optimally designed to ensure the most effective joint formation, achieving or exceeding the hydraulic and structural requirements of standards. Sanqing Stainless fittings up to and including 54mm have a leading lip, whereas, the 76.1 mm and 108 mm press fittings do not.
