Coilhose Pneumatics 4214-ADJ Inline Air Regulator 150 Psi

Product Description

The COILHOSE PNEUMATICS 4214-ADJ is an inline adjustable air pressure regulator designed to maintain consistent downstream pressure in compressed air systems. Part of the Series 4214 lineup, this regulator features a 1/4 inch NPT port and handles inlet pressures up to 150 psi. It is compact and lightweight at 0.3 pounds, making it well suited for installation in tight pneumatic lines. Licensed pipefitters, industrial mechanics, and pneumatic system technicians typically install this type of regulator to protect downstream tools and equipment from pressure spikes or inconsistent supply pressure.

This inline regulator is appropriate for use in light-duty to medium-duty compressed air distribution systems found in automotive shops, manufacturing facilities, and general industrial environments. It fits into 1/4 inch NPT pneumatic lines and is intended for applications where localized pressure adjustment is required at or near the point of use, such as upstream of spray guns, air tools, or sensitive pneumatic actuators.

Key Features

• Adjustable pressure regulation up to 150 psi maximum
• 1/4 inch NPT end connections for standard pneumatic line integration
• Compact inline design at approximately 2.88 inches wide
• Lightweight construction at 0.3 pounds for easy in-line mounting
• Series 4214 product family for consistent replacement sourcing

Compatibility

Designed as an OEM-style inline replacement regulator for 1/4 inch NPT compressed air distribution lines in light to medium industrial pneumatic systems.

Installation Notes

Installation should be performed by a qualified pneumatic technician or pipefitter. Depressurize and lock out the air supply completely before removing any existing regulator or making connections. Apply thread sealant tape to NPT threads per standard practice, taking care not to obstruct the port opening. Verify that inlet pressure does not exceed the 150 psi rated maximum before returning the system to service.
