PURCHASED A PUMA PK-65 PUMP. AFTER VIEWING THE PUMA WEBSITE AND THE CS WEBSITE IT WAS DETERMINED THERE WAS A MAX RPM DISCREPANCY. I HAD ALREADY ORDERED A 3.5 INCH PULLEY, BUT IT WAS DETERMINED AFTER DISCUSSION, I NEEDED A 4 INCH. COMPRESSOR SOURCE ACKNOWLEDGED THE ERROR AND I WAS ABLE TO SEND THE WRONG ADVISED PULLEY BACK FREE OF CHARGE AND GET THE CORRECT ONE. SHIPPING WAS VERY VERY FAST AND APPRECIATIVE. THESE FOLKS ARE GREAT, BUT,I CANT SAY THE SAME FOR THE PUMP. THE WEBSITE SAYS 14-22 SCFM BUT I ONLY GOT 13.8 AT 90PSI USING THE WEBSITE CALCULATOR. I WAS HOPING FOR A BIT MORE, BUT I WILL DEAL WITH IT. I WISH I HAD WENT A DIFFERENT ROUTE ON THAT. BUT, WITH THAT BEING SAID, THE CUSTOMER SERVICE WAS SECOND TO NONE AND I WOULD GLADLY BUY FROM THESE FOLKS AGAIN.
In Tank Brass Air Compressor Check Valve 1/2" Male NPT x 3/4" Compression
One new 3/4" compression x 1/2" NPT in-tank air compressor check valve. This style of check valve is usually screwed directly into the air tank, then the main line coming off the compressor pump is connected to it. This valve prevents back flow, which is tank pressure going back to the pump when the compressor is shut off. This valve comes equipped with a 1/8" female NPT port on the side of it. This port is typically used for an unloader line. If an unloader line is not needed with your application it can just be plugged. This is a top quality valve that is made in the USA!
Specifications:
• Total Valve Length: 2-3/4"
• Tank Threads: 1/2" Male NPT
• Compressor Line Input Threads: 3/4" Compression
• Unloader Line: 1/8" Female NPT
• Made in the USA
