VALUE VHB-2 – 1/2" Vacuum Pump Hose for Fast Evacuation, 1/2" × 1/4" SAE

VALUE VHB-2 is a 1/2" vacuum pump hose designed for fast and efficient evacuation of refrigeration and air-conditioning systems. With a length of 180 cm and a 1/2" × 1/4" SAE connection, it is suitable for professional service use.

Main product description:
The VALUE VHB-2 vacuum pump hose belongs to the Big Boy High-Flow Evacuation Hoses series, designed for fast and efficient evacuation of refrigeration and air-conditioning circuits. Thanks to its 1/2" diameter, the hose supports higher flow during evacuation, which can help reduce the time required to evacuate the system compared with standard narrower service hoses.

The VHB-2 model has a length of 180 cm and a 1/2" × 1/4" SAE connection. This configuration is suitable for connecting a vacuum pump, service tool or refrigeration circuit, depending on the specific service setup. The hose is intended for professional use in refrigeration and air-conditioning service, where reliability, sufficient flow and low permeation are important.

According to the technical datasheet, the hose has a four-layer construction with low permeation, a working pressure of 640 psi and a burst pressure of 3200 psi. Its vacuum rating of 20 microns makes it a suitable accessory for system evacuation during service and installation work. For best evacuation performance, the manufacturer recommends using it with the VALUE VCR1 valve core removal tool.
