Cavagna 1009500251 Propane Adapter 1-3/4 F Acme X 3/4 Fnpt

Product Description

The CAVAGNA 1009500251 is a propane cylinder adapter designed to connect a 1-3/4 inch female ACME fitting to a 3/4 inch female NPT outlet. This type of adapter is commonly used in LP gas systems to transition between the standard ACME connection found on propane cylinders and downstream NPT-threaded components such as regulators, manifolds, or supply lines. Licensed plumbers and qualified LP gas technicians are the typical installers. The fitting bridges two of the most common thread standards in propane service, making it a practical component in both portable and stationary LP installations.

This adapter suits residential and light commercial propane applications where a propane cylinder outlet must interface with NPT-threaded equipment. Typical scenarios include bulk cylinder hookups, temporary LP supply connections, and service or transfer operations requiring an ACME-to-NPT transition. The 1-3/4 inch female ACME thread is the standard connection found on most DOT propane cylinders used in the United States, while the 3/4 inch female NPT side accepts standard threaded fittings common throughout the gas supply chain.

Key Features

• 1-3/4 inch female ACME inlet matches standard DOT propane cylinder valve outlets
• 3/4 inch female NPT outlet connects to regulators, manifolds, and NPT-threaded supply components
• ACME-to-NPT transition covers one of the most common connection conversions in LP gas service
• Compact adapter form factor for straightforward inline installation

Compatibility

Designed as a standard LP gas adapter for use with propane cylinders featuring a 1-3/4 inch female ACME valve outlet and downstream components with 3/4 inch female NPT connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified LP gas technician in accordance with NFPA 58 and applicable local codes. Shut off all gas supply and relieve system pressure before connecting or disconnecting the adapter. Use an appropriate thread sealant rated for LP gas service on the NPT side only — ACME threads are a mechanical seal and do not require sealant. Leak-test all connections with an approved gas leak detection solution before returning the system to service.
