Brass Compression Nut 3/4 Inch

This pack contains ten brass compression nuts designed for 3/4 inch tube connections. They meet SAE and DOT FMVSS 571/112 standards for pressure applications. Each nut is rated for 150 PSI working pressure. Suitable for installers needing compliant brass fittings.

Check Tube Size and Pressure Rating

Verify that your tubing measures exactly 3/4 inch outer diameter before ordering. Confirm the system operating pressure does not exceed 150 PSI. Ensure the temperature range of -40 to 200 F covers your environment. These nuts use a compression connection for nylon tube.

Replaces Worn Brass Compression Nuts

Use this pack to replace damaged or corroded brass compression nuts on existing lines. The jump is worthwhile when original fittings show leakage or thread wear. Ten pieces allow multiple connection points to be refreshed at once. Ideal for maintenance kits requiring SAE and DOT compliant hardware.

Questions about this item

What comes in the pack and do I need ferrules or sleeves for the 3/4 inch compression connection?

The pack contains ten brass compression nuts for 3/4 inch tube size. Ferrules or sleeves for the nylon tube connection are not included and must be purchased separately.

How do I decide between this 150 PSI brass nut and a higher-pressure fitting?

Choose this nut when the system operates at or below 150 PSI and within the -40 to 200 °F range; it meets SAE and DOT FMVSS 571/112 standards for compression nylon tube connections.

What does the 150 PSI rating mean once the nut is installed on a solar thermal line?

It indicates the maximum working pressure the brass compression nut is designed to seal at temperatures between -40 and 200 °F when used with compatible nylon tubing and proper ferrules.
