Mueller Industries A17533 Valve

Experienced contractors know that reliability in the field depends on using exact-spec components. The Mueller Industries A17533 is a professional-grade 1 3/8 4-bolt mounting swt kit engineered for high-demand refrigeration and air conditioning systems. This assembly serves as the direct replacement for B32808, ensuring a seamless transition during compressor service or system retrofits without the need for piping modifications. Constructed from heavy-duty brass, the Mueller A17533 valve kit is designed to provide a leak-proof, high-stability connection that withstands vibration in commercial refrigeration valve applications.

This 4-bolt mounting kit is rated for a Maximum Abnormal Pressure (MAP) of 700 psig and maintains performance across a wide continuous operating temperature range of -40°F to 300°F. The 1 3/8" sweat connection and flat gasket surface are precision-machined for optimal flow and minimal pressure drop. Whether you are performing a compressor valve replacement or managing a preventative maintenance schedule, the A17533 Mueller provides the mechanical integrity required for long-term system efficiency and is fully compatible with common HFC, HCFC, and HFO refrigerants.

• OEM Compatibility: Functional direct replacement for B32808 for simplified field service.
• Durable Construction: Forged brass body with asbestos-free valve packing for superior environmental resistance.
• High Pressure Rating: Engineered to handle up to 700 psig, suitable for modern high-pressure refrigerants.
• Secure Mounting: The 4-bolt flange design eliminates movement and reduces stress on solder joints.

Is the Mueller A17533 compatible with R-410A?
Yes, it is UL/cUL recognized and rated for 700 psig, making it suitable for high-pressure R-410A systems and other common refrigerants.

Does this kit include the gasket and bolts?
Technicians generally expect the full kit (valve, gasket, and mounting bolts) for a standard 4-bolt service; however, always verify the specific package contents for your installation needs.

Can I use this to replace an older B32808 model?
Absolutely. The A17533 is the current manufacturer-designated replacement for the legacy B32808 part number.
