Maxitrol KR-11112 Seal Cap

The Maxitrol KR-11112 is a critical field-service component designed for maintaining the pneumatic integrity of RV111 series and 210G series gas pressure regulators. This seal cap and gasket assembly serves as the primary barrier for the regulator’s adjustment stack, preventing atmospheric contamination and unauthorized set-point tampering. Engineered to OEM technical specifications, the kit includes a high-grade nitrile gasket that ensures a positive, leak-proof seal under standard operating pressures found in commercial and industrial gas trains. For technicians performing routine maintenance or manifold upgrades, utilizing a genuine Maxitrol replacement part is essential for preserving the regulator's response characteristics and preventing vent-hole leakage. The KR-11112 provides a precise fit for the RV111 and 210G models, ensuring that the internal spring tension remains consistent and protected from environmental debris or moisture ingress during long-term operation.

• OEM Compatibility: Precision-molded for an exact fit on RV111 and 210G series regulators.
• Pneumatic Integrity: Included gasket provides an airtight seal to maintain stable gas pressure regulation.
• Contamination Protection: Shields the adjustment screw and internal components from dust, grease, and moisture.
• Verified Reliability: Manufactured to Maxitrol’s rigorous standards for industrial gas control applications.

• Does this cap fit the smaller RV48 series? No, the KR-11112 is specifically sized for the larger RV111 and 210G stacks; refer to the KR-4812 for smaller chassis.
• Is the gasket included in the kit? Yes, this part number comes complete with the necessary replacement gasket for a full seal.
• Can this be tightened by hand? While hand-tightening is a start, a wrench is recommended to properly compress the gasket for a gas-tight seal.
