How to use Compression fitting with brass Nut, Collar, and tube Insert
Compression fitting is used to connect the PVC tubing to the threaded metal inlet with a tapered open
end, such as the refrigerator water inlet, drinking faucet water inlet, etc.
Figure 4
1.
Slide the Nut, Collar onto the end of tubing
2.
Fully insert the Insert into the open end of tubing
3.
Slide the Collar to be close to Insert and fit into the tapered open end of the thread matal inlet.
4.
Screw on the Nut and tight it up. The Nut compresses the plastic Collar onto the tapered matal
surface and creates a water seal between them while the Insert hardens the tubing.
How to drill a hole on sink or counter-top
1.
It’s highly recommended to watch the YouTube video “How To Drill Faucet Holes.”
2.
Choose a half inch Diamond Core Bit for granite, and a titanium drill bit for steel. Do NOT use
a hammer drill on nature stone, glass, and ceramic.
3.
An indent should be made with a punch on steel before drilling to help guide the bit.
4.
Use caution when drilling on a Porcelain sink, as it could be easily chipped. Set drill speed on
slow. Press the bit downward firmly until breaking through the slippery surface.
5.
Use coolant to disperse heat. Choose water for granite, and oil for steel. Use the Water Suction
Cup to hold coolant inside and prevent the drill bit from slipping.
6.
Starting at slowest speed, hold the drill firmly and vertically and prevent the drill bit from
slipping on the counter.
7.
Once breaking through the smooth surface, swirl the drill a little to apply pressure in a circle
evenly.
8.
Be patient and deliberate. It can take 20 – 40 minutes to drill through one inch.
