Parker 25-787 Pneumatic Hose Coupling 3/8 Inch Industrial

Product Description

The PARKER 25-787 is a threaded pneumatic hose coupling designed for use in compressed air and pneumatic tool applications. Built from steel, this coupler features a 3/8-18 inch thread and a 3/8 inch body diameter, conforming to the Industrial Interchange standard — one of the most widely used coupling formats in shop and industrial environments. It is installed by HVAC technicians, industrial maintenance mechanics, and pneumatic system technicians who need a reliable, interchangeable connection point between air hoses, tools, and supply lines.

This coupling is suited for light to medium-duty pneumatic systems where Industrial Interchange compatibility is required. Typical applications include compressed air distribution in mechanical rooms, service bays, and equipment rooms. The threaded connection style allows for secure integration into existing pneumatic plumbing setups. Its steel construction makes it appropriate for general industrial and commercial service environments where durability and interchangeability with standard Industrial Interchange components are priorities.

Key Features

• Industrial Interchange standard for broad compatibility with existing pneumatic tool and hose systems
• 3/8-18 inch threaded connection for secure, leak-resistant installation
• 3/8 inch body diameter suits common mid-range pneumatic hose sizes
• Steel construction provides durability in shop and industrial service conditions
• Compact form factor fits tight installation points in pneumatic plumbing runs

Compatibility

Designed as an OEM-style replacement or service coupling for pneumatic systems using Industrial Interchange standard couplers with a 3/8 inch body size and 3/8-18 inch threaded connections.

Installation Notes

Installation is typically performed by a qualified industrial mechanic or HVAC service technician. Depressurize and lock out the compressed air supply completely before removing or installing any pneumatic coupling. Apply thread sealant appropriate for pneumatic service and verify thread engagement before restoring system pressure. Do not overtighten threaded connections; follow standard pneumatic fitting practices for the material and thread size.
