Here is a 2 pack of rubber replacement diaphragms for the Central Pneumatic Industrial Air Filter Regulator Unit that is sold at Harbor Freight. The Harbor Freight item number is 68247. The rubber diaphragm that comes in the unit starts leaking because itcracks/splits after a certain amount of time, and you can hearthe unit hissing air. Make sure you have the air supply closedto your regulator before attempting to change the diaphragm. The last picture shows what the unit that Harbor Freight sells looks like, make sure your unit looks like the one in the picture. The last picture is for reference only-you will not be receiving a regulator unit, this listing is just for two replacement rubber diaphragms. ***One note on the diaphragm: It seems like there were possibly a couple generations/versions of diaphragms that came in these regulators. The diaphragm that I am selling is the same size and thickness as the diaphragm in the regulator that I have. The diaphragm being sold here is 1/16" thick and 2" in diameter. The outer diameter may need to be trimmed a little to install.*** What you see is what you will be receiving. Thanks for looking and feel free to ask any questions. Free shipping to 48 continental US states only. Thanks.
