Alemite AL317400 Relief Fitting 1/4 Psi 1/8 Inch

Product Description

The ALEMITE AL317400 is a relief fitting designed to regulate and vent excess pressure in lubrication and fluid delivery systems. It is rated at 1/4 PSI relief pressure and features a 1/8 inch connection size, making it suitable for low-pressure grease or oil line applications. This fitting provides a passive pressure relief function, protecting downstream components from overpressure conditions. It is typically installed by lubrication technicians, millwrights, or maintenance professionals servicing industrial or fleet lubrication systems. The compact, single-unit form factor allows straightforward integration into existing line assemblies.

The AL317400 is used in centralized lubrication systems, grease distribution lines, and fluid handling assemblies where controlled pressure relief is required. Its 1/8 inch port size fits standard low-pressure lubrication fittings commonly found in industrial machinery, fleet vehicles, and manufacturing equipment. This fitting is sold individually and is well suited for maintenance, repair, and overhaul work where a single point replacement is needed without purchasing bulk assemblies.

Key Features

• 1/4 PSI relief pressure rating for low-pressure lubrication line protection
• 1/8 inch connection size compatible with standard lubrication line fittings
• Compact single-unit design for drop-in line replacement
• Passive relief function requires no external actuation or adjustment
• Lightweight construction at 0.01 pounds for use in space-constrained assemblies

Compatibility

Designed as an OEM-style replacement relief fitting for low-pressure lubrication and fluid distribution line assemblies using 1/8 inch port connections.

Installation Notes

Installation should be performed by a qualified lubrication technician or maintenance professional. Depressurize and lock out the lubrication system before removing or installing any fittings. Use appropriate thread sealant on the 1/8 inch connection as required by the system design. Do not exceed the rated relief pressure by installing this fitting in systems operating above its design threshold.
