Bluesky MISC GDR-4272 3/8 NPT to 1/8 NPT Reducing Thread Adapter Fitting

The Bluesky MISC GDR-4272 is a 3/8 NPT to 1/8 NPT reducing thread adapter designed to connect components with mismatched NPT pipe thread sizes. This fitting allows a device or sensor with a 1/8-27 NPT male thread to be installed into a 3/8-18 NPT female port, or conversely adapts a 3/8 NPT male side to a 1/8 NPT female port, depending on configuration.

This type of adapter is widely used in automotive, marine, RV, and powersports applications for routing oil pressure, fuel pressure, air pressure, or coolant temperature sensors and gauges to existing ports of a different thread size.

Key Features:

• Converts between 3/8 NPT and 1/8 NPT pipe thread sizes
• Compact reducer/bushing design for tight installation spaces
• Compatible with oil pressure, fuel pressure, air pressure, and similar sensor applications
• Standard NPT tapered thread form for reliable, leak-resistant sealing with thread sealant or PTFE tape
• Suitable for use in automotive, marine, RV, and powersports fluid and pressure systems

Apply thread sealant or PTFE tape to male threads before installation to ensure a proper seal. The GDR-4272 is a straightforward, reliable solution for adapting NPT thread sizes in plumbing, hydraulic, and pneumatic installations.
