SF4450 Replacement

This valve core is used in sealed-system refrigeration and air conditioning units. It allows technicians to charge or service refrigerant lines while maintaining a seal.

SF4450 Features

Functions as a core insert in Schrader valves, enabling refrigerant flow when service tools engage it and sealing it when idle.

Ships with a Teflon (or neoprene) seal for leak resistance under system pressures.

Built to precise dimensional tolerances (thread pitch, cone seating) to match industry-standard refrigeration valves.

Compatible with most refrigerants (e.g. R-134a, R-22, etc.) and replaces older core numbers like SF1515.

Commonly used in household refrigerators, freezers, dehumidifiers, and HVAC systems’ service ports.

Always verify compatibility with your equipment’s valve port and refrigerant type before installing.
