Explanation of Reduced Barrier Fittings:

Reduced barrier fittings have the same inner diameter as standard barrier fittings, but the outer diameter is smaller. In other words the thickness of reduced barrier hose has a reduced outer diameter compared to standard barrier hose.

If you need reduced barrier fittings choose the fitting part numbers with a SR (Steel) or RB (Aluminum) as the prefix.

Reduced Barrier Hose:

The reduced barrier hose is a thinner wall construction that offers improved flexibility and reduced weight without sacrificing permeation resistance and burst strength. The hose is compatible with most common refrigerants including R12 and R134a. The hose is constructed with a single braid of polyester reinforcement. This hose is designed to exceed both SAE J2064 and OEM manufacturer requirements.
