YELLOW JACKET 42036 Series 41 2-Valve HVAC Manifold with 3-1/8" 1% Gauges and 60" R/Y/B Hoses — A2L Compatible

The YELLOW JACKET 42036 Series 41 2-valve manifold is a rugged, A2L-compatible service manifold with high-visibility 3-1/8" gauges and three 60" PLUS II hoses for R-32, 454B, and 410A refrigerants.

This service manifold combines proven YELLOW JACKET durability with larger, precision instruments and long color-coded hoses to simplify charging and diagnostics on modern refrigeration and A/C systems. Built for technicians who need accurate readings under field conditions, the 42036 integrates 1% accuracy gauges, sliding double O-ring pistons for long life, and A2L refrigerant compatibility so you can work safely and efficiently across common low-GWP refrigerants.

How accurate are the gauges and why does that matter?

The Series 41 manifold is equipped with 3-1/8" (80mm) gauges rated at Class 1 accuracy (±1% over the full scale). That level of precision helps technicians charge systems to tighter tolerances and diagnose performance issues more reliably than lower-accuracy tools. Larger gauges also improve readability under shop, truck, or rooftop lighting.

• 3-1/8" polycarbonate crystal faces for impact resistance
• Color-coded pressure arcs and refrigerant scales for quick interpretation
• 1% accuracy across the full pressure range for critical charge work

What refrigerants and system types is this manifold suited for?

The 42036 is set up for R‑32, R‑454B and R‑410A service and is A2L compatible, making it suitable for many modern low‑GWP and HFC systems. Use it for residential and commercial air conditioning, light commercial refrigeration, and retrofit projects where those refrigerants are specified. Always follow refrigerant handling and safety regulations when servicing systems with flammable refrigerants.

• Marked scales for R‑32, R‑454B and R‑410A on the gauge faces
• A2L compatibility for safer use on lower-flammability refrigerants
• Ideal for both new installs and maintenance of charged systems

What durability and usability features help on the job?

The manifold assembly is built to withstand everyday field use with a steel case, sliding double O‑ring pistons to reduce wear, and long 60" PLUS II hoses that resist kinking and cuts. Color-coded red/yellow/blue hoses speed hook-up and reduce mistakes, while the rugged construction resists impacts and keeps gauges readable over time.

• Rugged steel gauge case with durable polycarbonate crystals
• Sliding double O‑ring piston design for smoother operation and longer life
• Three 60" PLUS II 1/4" hoses (R/Y/B) minimize reach issues on larger equipment

How does this manifold improve workflow during service calls?

Large, color-coded gauges and long hoses reduce set-up time and clarify readings so technicians can complete diagnostics and charging faster. The 2-valve design keeps the tool lightweight and straightforward for common pressure measurements and vacuum operations. Compatibility with common modern refrigerants avoids the need for multiple manifold sets on mixed‑fleet service routes.

• Faster hook-up with color-matched hoses and scales
• Clear, readable gauges lower the chance of misreads under varied lighting
• Two-valve layout balances simplicity with essential control for most tasks

Who is this for: The YELLOW JACKET 42036 Series 41 manifold is aimed at HVAC/R service technicians and contractors who demand accurate, durable tools for working with modern refrigerants including R‑32, R‑454B and R‑410A. It's a solid choice for field service, installations, and retrofit work where clear gauges, long hose reach, and long-term reliability reduce downtime and improve job accuracy.
