UPR 15.82mm male to 12an ORB male valve cover fitting for catch can or breather tanks. These AN ORB style fittings thread into any aftermarket valve cover that uses a 12AN ORB female ports and allows you to connect a UPR 5/8" Plug N Play fitting to the 15.82mm male end that gives you a secure and clean connection to your catch can or breather tanks. Custom hex allows for easy installation and removal. The fittings include restrictor jets for use with any OEM style PCV system. The restrictor would be used with a catch can that is connected to vacuum to prevent low vacuum signal (install the smaller restrictor for more vacuum, larger for less vacuum) and over filling the catch can. Restrictors would not be used with vent to atmosphere breather tanks or on the 'fresh air side' of the PCV system.
These can also be used on UPR or any catch can / breather tanks using -12 ORB threads.
