Yellow Jacket 21985 Plus II Hose 1/4ft Flare Fittings Pack of 3

In this review of the Yellow Jacket 21985 Plus II Hose Pack, the bottom line is simple: HVAC technicians and serious DIYers who need reliable, low-permeation service hoses will find real value here. The set of three 60' red, yellow and blue hoses delivers strong leak resistance and a rated 4000 psi minimum burst strength, and the built-in nylon moisture barrier targets the common problem of refrigerant contamination. For anyone charging, evacuating or testing refrigeration systems, these hoses combine practical working temperatures and robust fittings into a package that performs as expected.

Key Features

• Nylon moisture barrier: Reduces moisture migration into refrigerant lines so expensive refrigerant remains cleaner during service.
• High pressure rating: Each 1/4' Plus II hose is rated to 4000 psi minimum burst which adds a margin of safety for heavy-duty tasks.
• Working pressure and temperature: The hoses handle up to 800 psi working pressure and operate from -20o to 180oF, covering most service conditions.
• Color coded set: The red, yellow and blue trio simplifies hookups and reduces cross-connection mistakes on the manifold.
• Standard 1/4' flare fittings: Common fitting size ensures compatibility with standard HVAC equipment and gauges.
• Compact packaging: The pack ships in a small 2.0' cube and weighs about 2 lb, making it easy to store and transport.

Who It's For

The Yellow Jacket 21985 set is aimed at professional HVAC technicians and experienced homeowners who routinely service refrigeration or air conditioning systems and need hoses that stand up to repeated use. The hose set's combination of a moisture barrier and robust pressure ratings makes it a sensible choice for work that involves cfc, hcfc and hfc refrigerants.

Less experienced users who rarely touch refrigerant systems may find a simpler or shorter hose adequate; similarly, those needing longer reach than 60' per hose or specialty fittings beyond standard 1/4' flare should look elsewhere. For general maintenance and standard service tasks, however, this pack is well suited.

Pros & Cons

Pros

• Strong leak resistance and sealability that customers consistently praise, reducing wasted refrigerant.
• High burst rating and reliable working pressure for safety and durability in demanding jobs.
• Nylon permeation barrier meets SAE J2196 requirements for cfc, hcfc and hfc refrigerants, preventing contamination.
• Color coded hoses simplify setup and minimize connection errors.

Cons

• Durability opinions are mixed among users, so heavy daily use may show wear sooner than premium specialty hoses.
• Package contains three 60' hoses only, so those needing different lengths or fittings will need alternatives.
