Parker VC-001 Access Valve Core 0.25 Inch Tube Od

Product Description

The PARKER VC-001 is a replacement access valve core designed for use with Parker brass access valves in refrigeration and HVAC systems. This small but critical component seats inside the access valve body to control refrigerant flow and maintain a pressure-tight seal during service operations. The VC-001 features a 0.25 inch tube outside diameter and weighs just 0.01 pounds. HVAC technicians install this core during routine maintenance, after a valve core failure, or whenever a system access port must be resealed to prevent refrigerant loss.

This valve core is suited for residential and light commercial refrigeration and air conditioning service work. It fits Parker brass access valve bodies and is typically installed at service ports on refrigerant lines, condensing units, and evaporator coils. Technicians working with R-410A, R-22, or other common refrigerants will encounter this style of core in standard Schrader-type access fittings throughout the system.

Key Features

Compatibility

Designed as a replacement access valve core for Parker brass access valves. Specific compatible valve body model numbers were not provided in available product data — confirm fitment against the Parker brass access valve model on site before installation.

Installation Notes

Installation of an access valve core should be performed by a licensed HVAC technician certified to handle refrigerants under EPA Section 608 regulations. Before replacing the core, recover system refrigerant and relieve line pressure to zero psi to prevent injury. Use a dedicated valve core removal and installation tool to avoid damaging the valve seat threads. Once the new core is seated and torqued per the valve body manufacturer specification, leak-check the fitting before recharging the system.
