Solar Male Connector 1/4-18 Thread

The Eaton 1868X8X4 is a brass male connector designed for solar and compressed-air systems using a 1/4-18 pipe thread. It suits installers who need a quick-connect fitting rated for 150 PSI and a temperature range of -40 to 200 F.

Brass Construction and EPDM Gasket

The brass body resists corrosion in outdoor solar arrays while the ethylene propylene rubber gasket maintains sealing integrity across the full temperature range. Compliance with DOT FMVSS 571.106 and SAE J1165 confirms suitability for air-brake and push-connect applications.

1/2 In Tube Capacity and 150 PSI Limit

This fitting comfortably handles 1/2 inch tubing at pressures up to 150 PSI within the stated temperature envelope. It is not intended for higher-pressure hydraulic circuits or tube sizes beyond the specified 1/2 inch dimension.

Questions about this item

Will the ethylene propylene rubber gasket on this 1868X8X4 connector need periodic replacement?

The gasket is rated for a temperature range of -40 to 200 F and meets DOT FMVSS 571.106 and SAE J1165 standards, so it is designed for long service without scheduled replacement under normal conditions.

What pressure limit will be reached first if this brass connector runs continuously at its maximum 150 PSI rating?

The connector is rated for 150 PSI working pressure; sustained operation at that pressure will not exceed its design limit, and the brass body with quick-connect interface maintains the seal within the specified range.

How much heat does this male connector generate when used all day in a solar installation?

As a passive brass fitting with no electrical or moving parts, it produces no measurable heat; the only thermal factor is the ambient temperature staying within the -40 to 200 F operating range.
