Brass compression nut for solar fluid lines

The Eaton Weatherhead 1461X8 brass compression nut connects 1/2 inch nylon tubing in solar thermal installations. It meets SAE and DOT FMVSS 571/115 standards for pressure-rated service. Each pack contains ten nuts ready for field assembly.

Fits 1/2 inch nylon tube at up to 150 PSI

The nut seals directly onto 1/2 inch compression nylon tube without soldering or special tools. Brass construction resists corrosion from glycol-based heat-transfer fluids. The design frees installers from threading pipe or using flare fittings in tight collector arrays.

Rated from -40 to 200 F for continuous exposure

Brass maintains sealing force across the full temperature range without creep or stress relaxation. The nut holds 150 PSI during prolonged stagnation events when collectors exceed operating temperatures. SAE and DOT compliance confirms performance under sustained thermal cycling.

Questions about this item

What temperature range can the brass compression nut handle under sustained use?

The nut operates from minus 40 to 200 F, so the upper limit of 200 F is the first boundary you reach under continuous high-temperature exposure.

How much heat does the fitting generate when pressurised to 150 PSI all day?

The brass nut itself produces no heat; it simply contains the fluid at up to 150 PSI and the stated temperature range without adding thermal load.

Which tubing size and type must I already have for these 1/2 inch compression nuts to seal?

You need 1/2 inch nylon tube; the compression connection is designed specifically for that tube size and material.
