Alemite AL47200 Grease Fitting 1/8 Ptf Relief 1-5 Psi

Product Description

The ALEMITE AL47200 is a relief-type grease fitting with a 1/8 PTF thread connection and a relief pressure range of 1 to 5 psi. This fitting is designed to vent excess grease pressure during lubrication, preventing over-greasing of bearings and sealed components. It is installed directly into bearing housings, industrial equipment, and machinery lubrication points where controlled grease purging is required. Licensed technicians and equipment maintenance professionals working with industrial or commercial lubrication systems are the primary installers of this fitting.

This fitting is suited for use in industrial maintenance applications where over-pressurization of bearing cavities or grease-packed housings is a concern. The relief function allows excess lubricant to escape at a controlled threshold, reducing the risk of seal damage in electric motors, conveyor systems, pumps, and similar rotating equipment. It is compatible with standard grease gun delivery systems and threaded fitting ports.

Key Features

• Relief valve function vents grease at 1 to 5 psi to prevent seal over-pressurization
• 1/8 PTF threaded connection for standard fitting ports
• Compact, lightweight design at 0.01 pounds per unit
• Sold individually — confirm quantity requirements before ordering

Compatibility

Designed as a direct-install relief grease fitting for equipment bearing housings and lubrication points accepting a 1/8 PTF threaded port.

Installation Notes

Installation is performed by maintenance technicians and industrial service professionals using standard hand tools appropriate for threaded fittings. De-energize and lock out all equipment before servicing lubrication points on rotating machinery. Apply thread sealant as required by the equipment manufacturer and applicable maintenance procedures. Do not exceed the rated thread engagement depth to avoid damaging the receiving port.
