Yellow Jacket Blue 4 PLUS2 Hose 21248

The Yellow Jacket 21248 is a 4 foot blue PLUS II charging hose for low side connections.

Hose gaskets are the most frequently overlooked consumable in refrigeration service, and they account for a large share of the leaks technicians spend time chasing.

The gasket at each hose end seals against the service port face. Over time it hardens, takes a permanent set, cracks, or is simply lost when the hose is disconnected. A hose with a failed gasket leaks continuously while connected, which wastes refrigerant, gives misleading readings during a pressure test, and makes a vacuum impossible to hold.

The last of these is particularly troublesome, because a technician attempting to evacuate a system with a leaking hose gasket will conclude the system has a leak and spend considerable time searching for it.

Checking gaskets before connecting, and carrying replacements, prevents this. Replacement gaskets are inexpensive and take moments to fit.

A useful discipline is to evacuate the manifold and hoses alone, isolated from the system, when a vacuum will not hold. If the manifold alone will not hold vacuum, the leak is in the equipment rather than the system.

Applications include refrigeration and air conditioning service and charging.
