The GRACO 161077 is a fitting, union, and straight adapter designed to connect different pipe sizes and types within GRACO equipment. It is commonly used as a swivel adapter to facilitate flexible connections between 1/2-inch NPT (female) and 3/8-inch NPS (female) threaded components. Material is not specified in available sources, but it is typically constructed from durable metals for industrial use. Its intended function is to provide a secure, leak-free connection in fluid transfer systems, such as lubrication or spray equipment.

Key Features:

• Fitting, Union, Adapter, Straight
• 1/2-inch NPT(f) x 3/8-inch NPS(f)
• Compatible with GRACO equipment requiring 1/2-inch NPT(f) to 3/8-inch NPS(f) connections
• Swivel design for flexible installation
• Reliable, leak-free connection
• Ease of maintenance due to standard threading

Applications:
Used in fluid transfer systems such as lubrication, spray, and maintenance equipment where flexible or secure pipe connections are required.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance within GRACO systems.
• Ensure threads are clean and free of debris before installation
• Use appropriate thread sealant or tape for leak prevention
• Hand-tighten before final torque to avoid cross-threading
• Inspect regularly for leaks or wear and replace as needed
