Comparing Colors of ACME Type 1 Propane Connectors for Function  


Hi there.. Are there any regulations or standards that govern what the various colors mean for these ACME connectors? THANKS!


Expert Reply:

There are differences that the colors reference for the Type 1 Propane connectors based on the spring tension and flow rate. The light green connectors are rated for Rated for 200,000 Btu per hour. The black are rated for 70,000-100,000 Btu per hour. The dark green are rated for 450,000-500,000 Btu per hour. The Red connector is the strongest spring and is often used for high pressure adapters and T-fittings.

Here are some options of each:
Dark Green # 204052-MBS
Black # 204024-MBS
Light Green # CAM59923
Red # 103613-MBS

I've also linked an article and the page to your pigtail connection options.

want to replace the Black TYPE 1 connector with the Dark green Type 1 connector and attach to my existing hoses. I have a High capacity auto switching 2 stage regulator (345Kbtu) but the black type 1 connectors not letting allowing enough flow. I would like to reuse the 2 flexible pigtails that I have. the Type 1 connector end to the hose is a 1/4" npt fitting I believe.
