The GRACO 18150-4 is a push-to-connect fitting designed to join 1/4-inch male pipe thread (MPT) to 3/8-inch tube (TBE) in fluid systems. While specific material details are not listed for this exact part, similar Prestolok fittings typically feature a composite or metal body with corrosion-resistant seals, intended for reliable, leak-free connections in industrial and pneumatic applications.

Key Features:

• Push-to-connect fitting
• 1/4MPT X 3/8TBE
• Designed for use with compatible tubing and pipe threads in fluid systems
• Quick and secure push-to-connect installation
• Corrosion and chemical resistance (typical for Prestolok fittings)
• Reliable sealing for leak-free operation
• Ease of maintenance and replacement

Applications:
Used in industrial, pneumatic, and fluid handling systems for connecting tubing to threaded ports. Suitable for air, cutting fluids, inert gases, and vacuum applications where reliable, leak-free connections are required.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance within GRACO equipment.
• Ensure tubing and threads are clean and free from debris before installation
• Push tubing fully into the fitting until it clicks into place
• Check for secure connection and absence of leaks after installation
• Follow manufacturer guidelines for pressure and temperature limits
• Regularly inspect fittings for signs of wear or damage
• Replace seals or fittings if leaks are detected
• Use only compatible tubing and accessories as specified by GRACO
