Can I use this seal cap on a 325-3 series regulator?
No, this specific seal cap is dimensioned for the 325-5 series and RV61 platforms. For smaller 325-3 units, you must utilize the corresponding seal cap size to ensure a proper gastight fit.

Does this seal cap function as a vent limiter?
The KR325E12 is a solid seal cap designed to close off the adjustment stack. It should not be confused with a vent limiting device (vLimiter) which is installed in the vent connection to manage diaphragm relief.

Is the gasket included with the cap?
Yes, the Maxitrol KR325E12 is supplied as a complete assembly featuring both the threaded cap and the necessary seating gasket.
