Ducane R100432-08 Service Valve 5/8 Inch Suction

Product Description

The DUCANE R100432-08 is a 5/8 inch suction-side service valve with a 45-degree angle configuration, designed for use in refrigerant circuit service and maintenance applications. This valve allows HVAC technicians to isolate the suction line during system service, enabling refrigerant recovery, pressure testing, and component replacement without a full system shutdown. The 45-degree body orientation is suited for installations where straight inline access is restricted. Licensed HVAC technicians performing refrigerant work or coil service are the primary installers of this valve.

This service valve is intended for use on the suction side of a refrigerant circuit where a 5/8 inch line connection is present. It is typically found in residential and light commercial split-system air conditioning and heat pump equipment. The 45-degree angle design accommodates tight equipment cabinet layouts and lateral line routing commonly encountered during field service.

Key Features

• 5/8 inch suction-side connection for standard residential and light commercial refrigerant line sizing
• 45-degree valve body angle for flexible installation in space-constrained equipment cabinets
• Service valve design allows line isolation for refrigerant recovery and system servicing
• OEM part number R100432-08 for direct DUCANE system replacement

Compatibility

Designed as an OEM-style replacement suction service valve for DUCANE refrigerant-circuit equipment requiring a 5/8 inch 45-degree service valve configuration.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician. Recover all refrigerant from the system before removing or replacing any service valve. Use proper brazing technique and procedures when making refrigerant line connections, and allow the joint to cool fully before pressurizing the system. Leak-test all connections with an approved electronic leak detector or nitrogen pressure test before recharging.
