Lincoln Electric 81495 Manual Drum Pump Nozzle 3/8 in Nptf

Product Description

The LINCOLN ELECTRIC 81495 is a non-metered manual dispense gun nozzle designed for continuous-flow grease and lubricant delivery in drum pump systems. Operating at up to 7,500 psi and flowing up to 25 cubic inches per minute, it delivers an unregulated, steady stream whenever system pressure is active. With fewer moving parts than metered dispense guns, it requires less maintenance and resists jamming or clogging under heavy-use conditions. Licensed HVAC techs, lubrication technicians, and industrial maintenance crews use this type of nozzle where high-volume, rapid grease delivery is the priority.

This nozzle suits applications where equipment requires constant flushing to remove debris or where large volumes of grease must be dispensed quickly. Its 3/8 inch NPTF inlet makes it a practical fit for standard drum pump setups in industrial, fleet maintenance, and heavy equipment service environments. Because there is no meter included, output volume is controlled by the operator through system pressure management rather than a metered mechanism. It is also referred to as a continuous flow valve in service documentation.

Key Features

• Non-metered continuous flow design delivers steady, unregulated grease output while system pressure is active
• Maximum flow rate of 25 cubic inches per minute supports high-volume lubrication tasks
• Rated for up to 7,500 psi maximum operating pressure
• 3/8 inch NPTF inlet provides a secure, leak-resistant threaded connection
• Fewer moving parts compared to metered guns means reduced maintenance and lower risk of clogging
• Manufactured in the USA (subject to change)

Compatibility

Designed as an OEM-style replacement or supplementary nozzle for drum pump grease dispensing systems that accept a 3/8 inch NPTF inlet connection.

Installation Notes

Installation should be performed by a qualified lubrication or maintenance technician familiar with high-pressure fluid dispensing systems. Depressurize the drum pump system completely before connecting or disconnecting the nozzle. Verify thread type compatibility — NPTF threads are not interchangeable with NPT threads without risk of leakage at high pressure. Inspect the inlet connection for proper seating before returning the system to service.
