Ship grease zerk fittings are small, threaded fittings used to deliver lubricant to moving parts on vessels. Lubrication systems ensure smooth operation by distributing grease to bearings, joints, and other machinery components. These systems reduce friction, prevent wear, and extend equipment lifespan in marine environments.

Ship Grease Zerk Fittings:

- Size: 1/4", 1/8", or metric equivalents (M6, M8, M10)

- Grade: NLGI 2 (standard), NLGI 1 or 3 for extreme conditions

- Viscosity: 100-150 cSt at 40°C (varies by grease type)

- Buoyancy: Not applicable (solid fittings)

- Material: Carbon steel, stainless steel (AISI 304/316), or brass

- Thread Type: NPT, BSPP, or metric threads

- Pressure Rating: Up to 10,000 psi (high-pressure variants)

Lubrication Systems:

- Size: Varies (manual, automatic, or centralized systems)

- Grade: Compatible with NLGI 0 to NLGI 3 grease

- Viscosity: 50-500 cSt at 40°C (depends on oil/grease used)

- Buoyancy: N/A (system components may float if sealed)

- Material: Steel, aluminum, or polymer housings

- Operating Pressure: 50-15,000 psi (system-dependent)

- Flow Rate: 0.1-30 liters/min (varies by pump type)

The product's compliance with maritime standards would depend on the specific standards it meets. Please check the product specifications or contact the manufacturer for detailed information regarding maritime compliance.
