Supco Valve Core Tools

Overview

The SUPCO sf4450 is a replacement valve core designed for use in refrigeration and air conditioning service valves. It features a Teflon seal, which provides reliable performance across a wide range of refrigerants. Valve cores are small but critical components — they control refrigerant flow through Schrader-style service ports and must seal completely to prevent leakage. This unit replaces the SF1515 valve core, which used a neoprene seal. The Teflon seal version is suited for technicians working with refrigerants that may degrade standard neoprene over time. The sf4450 is used in HVAC and refrigeration service work wherever Schrader valve cores are required. It is a common consumable for residential and light commercial systems during refrigerant recovery, evacuation, and recharge procedures. HVAC technicians keep valve cores on hand for servicing AC units, heat pumps, refrigeration cases, and other systems equipped with standard service port fittings.
