Maxitrol KR-4812 Seal Cap

The Maxitrol KR-4812 is a precision-engineered seal cap with gasket designed specifically for Maxitrol gas pressure regulators. This critical component ensures a gastight seal on the adjustment screw, maintaining consistent outlet pressure and preventing environmental contaminants from entering the regulator housing. Engineered for compatibility with RV47, RV48, RV52, and R500 series regulators, the KR-4812 provides a secure mechanical fit that meets strict field safety requirements. In commercial and industrial gas piping systems, replacing a missing or damaged seal cap is essential for maintaining the listed integrity of the regulator. The included gasket is manufactured from high-grade elastomers to resist degradation from fuel gases, ensuring long-term reliability in high-cycle environments. Whether you are performing routine maintenance on a Maxitrol RV48 or a large-scale R500 series valve, utilizing OEM regulator repair parts like the KR-4812 is the only way to ensure gas pressure regulator compatibility and performance according to engineering specifications.

• OEM Compatibility: Exact fit for Maxitrol RV47, RV48, RV52, and R500 series regulators.
• Secure Sealing: High-quality gasket prevents gas leakage at the adjustment tower.
• Durable Construction: Built to withstand the rigors of mechanical rooms and industrial gas trains.
• Field Reliability: Ensures the regulator remains tamper-resistant and maintains its setpoint.

Does the KR-4812 include the gasket?
Yes, this part number Includes the matching gasket required for a gastight seal on compatible Maxitrol series.

Is this seal cap compatible with the RV48LM or RV48LE models?
Yes, the KR-4812 fits the standard RV48 casting, including the LM and LE variants commonly found in commercial kitchens.

Why is a seal cap required for regulator operation?
The seal cap protects the calibration screw and prevents leakages in the event of a diaphragm rupture, while keeping debris out of the spring housing.
