Diaphragm for a Central Pneumatic Model 47065, any idea where can I buy one?
What diaphragm? Are you talking about the pressure switch?
Quick fix diaphragm…
I made the diaphragm from a bicycle inner tube cut square with scissors and punched with a small leather punch tool on hardwood backer board.
Reassembly is easier if you clamp the spring to keep it from pressing everything open. I used two medium hand spring clamps.
If you need a complete switch the OEM switch is on Amazon. It was under $8 at the time of this writing.
Pressure switch & diaphragm
Azben, good tip for the diaphragm. Might work for a regulator diaphragm as well.
Be aware that delivery of the switch you refer to could be a month or two.
Pressure switch for CP #47065
You are correct, that could take way too long. However, there is a similar switch with fulfillment by Amazon, meaning they have it at their warehouse already. You should get this one for a couple dollars more in only a week or less. Only two days for Prime members.
HF # 47065 Pressure Switch
Just ordered one from an Amazon store (Wessol) located in KY, not China. Cost $9.18, no tax or shipping, and will be here in a few days. Here’s the info: “New Heavy Duty Air Compressor Pressure Switch Control Valve 90 PSI -120 PSI
ESUMIC” and it lists a 3 year warranty!
