Maxitrol KR325C12 Seal Cap

The Maxitrol KR325C12 Seal Cap is a critical replacement component designed for use with 325 series gas regulators, including the 325-3, RV53, and R600Z models. This aluminum gas regulator cap includes the necessary replacement gasket to ensure a gas-tight seal, preventing leakage from the adjustment screw housing. Engineered for natural gas and LP applications, the KR325C12 maintains the integrity of the ANSI Z21.18 certified regulator body. In HVAC gas pressure regulation, any compromise in the seal cap can lead to pilot outages or inconsistent manifold pressure. This Maxitrol regulator part is essential for technicians performing maintenance on 2 psi piping systems or appliance regulators. By utilizing a die-cast aluminum construction, it provides the durability required for commercial and industrial gas trains while ensuring the internal loading spring remains protected from environmental contaminants and unauthorized tampering.

• Compatible with Maxitrol 325-3, RV53, and R600 Series gas regulators.
• Includes high-grade elastomer gasket for a reliable, leak-free seal.
• Constructed from corrosion-resistant aluminum for long-term field reliability.
• Ensures consistent outlet pressure by protecting the stack adjustment mechanism.
• Direct OEM replacement part ensures exact fitment and reduces installation downtime.

What happens if the gasket is missing from the KR325C12 seal cap?
Operating a 325 series regulator without the integrated gasket can lead to minor gas leakage or fluctuating delivery pressures, especially in high-demand gas trains.

Is the KR325C12 compatible with the 325-5 or 325-7 models?
No, this specific seal cap is sized for the smaller 3/8" and 1/2" NPT 325-3 and RV53 footprint. Larger regulators require specific caps tuned to their stack diameters.

Can this cap be used for outdoor regulator installations?
Yes, the aluminum construction is standard for exterior use, though a vent protector may also be required depending on local code and the specific regulator vent orientation.
