The 3/4" 10,000 PSI NPT Giant Button Head Grease Fitting is a critical maintenance component engineered specifically for high-pressure plug valves. Designed to facilitate the safe and efficient injection of heavy-duty sealants, lubricants, and valve flush materials under extreme pressure, this fitting ensures proper valve operation, prevents galling, and maintains a bubble-tight internal seal in rigorous upstream and midstream environments.

Manufactured from high-strength alloy steel (such as AISI 4140 or 316 Stainless Steel) and featuring precision-cut 3/4" National Pipe Threads (NPT), this fitting securely integrates into the valve body. It features a robust internal ball check valve mechanism, often supported by high-performance Inconel springs, which prevents the dangerous backflow of high-pressure wellbore fluids or gases during the greasing process. The giant button head profile provides a secure connection for heavy-duty, high-volume grease guns and hydraulic injection pumps.

 

Designed for uncompromising safety and reliability, this 3/4" plug valve grease fitting is an essential consumable for routine maintenance programs on critical oil and gas flowline manifolds.

Features & Benefits

  • 10,000 PSI Pressure Rating: Safely contains extreme internal valve pressures while allowing for high-pressure grease injection.

  • Giant Button Head Design: Provides a secure, heavy-duty engagement point for industrial grease couplers, preventing slip-offs under pressure.

  • Internal Ball Check Valve: Prevents hazardous back-pressure and fluid escape, protecting operators and equipment.

  • NACE MR0175 Compliant Options: Available in materials suitable for sour gas (H2S) service to prevent sulfide stress cracking.

  • Durable Construction: Built from premium alloy or stainless steel with protective plating to resist harsh environmental corrosion.

  • Direct Field Replacement: Engineered with standard 3/4" NPT threads to easily replace worn or damaged OEM plug valve fittings.
