Wow!!! There was a "Speed Bump" with my order when they went to crate up my pump they discovered that their provider had made changes to the pump. They contacted me with options and I chose to wait on the pump that I ordered. Communication and Follow Thru was flawless.
The pump arrived yesterday and it was the pump that I ordered. It looks like a quality replacement and it measures out matching the spec's on the Web site.
RapidAir FastPipe Straight Union Adapter - 3/4" FastPipe x 1/2" Male NPT - F1018
This 3/4" FastPipe x 1/2" male NTP adapter is used with 3/4" Fastpipe solid aluminum tubing allowing you to easily connect to your airpipe system. Rapid Air products provide superior air quality. Not only do they cool hot compressed air quickly for better filter performance, but there is also no corrosion in the pipe and fittings, meaning longer tool life. The double o-ring seals ensure a leak-free system with no gluing, threading, or soldering. MNPT Adapters allow you to expand or modify the system with ease. Note: this fitting is only compatible with RapidAir's FastPipe system which uses rigid aluminum tubing. It will not work with RapidAir's Maxline system which uses flexible lines and has a different outside diameter.
