What's the difference between Brass and Bronze?
Brasses are copper alloys in which zinc is the principal alloying addition.
Bronze may also contain specified quantities of lead, tin, manganese and silicon.

After tightening our "Q" series compression assembly, I can still rotate the fitting on the tube, 为什么?
This may be caused by one of two reasons.
1) The copper or PE tube is undersize. This instance requires the tube to be replaced.
2) The copper or PE is on the lower end of the tolerance. 如果发生这种情况, the compression joint is designed to cover the entire range of diameters and will seal and have sufficient pull out strength to do the job.
Reasons 为什么 the tube rotates in our other compression systems may vary.

Do we have a compression fitting for PEX tubing?
Our T-series and -22 Mac-Pak CTS size compression ends will work with SDR 9 PEX tubing manufactured in accordance with ASTM f876/F877 and CSA B137.5. McDonald compression ends are for use with cold water applications only and a properly sized insert stiffener is required, i.e. 麦当劳6131T或6133T. Standard McDonald installation instructions should be followed.

What is the pressure rating of our fittings?
As long as connections are being used on the correct pipe or tube and assembled per our instructions, the fittings are rated to what ever the pipe or tube is rated for.

Why are stab depths for plastic tube and/or pipe into compression fittings required?
1) To get enough length into the fitting to support the pipe or tube.
2) To make sure the pipe or tube is not inserted in too far as to prevent the insert stiffener from supporting the gripper of the compression nut.
3) To keep the pipe or tube from being inserted too far as to interfere with the operation of a valve or assembly.

What size are the lock wing holes in our ball valves?
Ball valves with 5/8" or 3/4" port balls have a 7/16" diameter hole. Ball valves with 1", 1 1/2", or 2" port balls have 1/2" diameter holes.
