Fitting Assembly Guidelines
For helical type tube and cone type packing (graphite, silicone, EPDM and NBR) fitting
- Step 1 : Cut Tube
Cut tube at right angle to tube length using an electric tube cutter.
Make sure the cut end to be clean and flat.
- Step 2 : Remove Burr on Tube End
Use stainless steel brush to remove all burr on tube cut-end.
- Step 3 : Assemble Nut
Put nut onto tube.
- Step 4 : Assemble Clamp Thread Ring
Put clamp thread ring on tube and screw in clock-wise.
- Step 5 : Assemble Threaded Cone Packing
Screw threaded cone packing onto tube until it doesn’t spin anymore. (Do Not screw the packing by force)
- Step 6 : Tighten Helical Type Clamp Thread Ring and Packing
Tighten Clamp Thread ring to meet threaded cone packing and fix it.(Double Nut Tightening)
- Step 7 : Assemble Socket
Put sealant on tapered thread of brass socket, then screw the socket into piping system or boiler with high torque using a crescent wrench.
- Step 8 : Assemble Fitting
Make a whole assembly set of tube, nut, stopper ring, DO NOT use sealant on parallel thread of unino nut!
- Step 9 : Tighten Nut
Tighten up the nut and complete the fitting assemble
