Parker 393P-4-4 is a compression x plug-in stem coupler made of brass. It is designed for high-pressure applications with a maximum pressure rating of 150 psi. The coupler features a metal-to-metal seal that provides reliability and safety under pressure. This fitting is ideal for use where solder type joints may not be suitable due to open flame restrictions.
Parker's coupler provides a durable connection that resists mechanical pull-out forces. It complies with SAE J512 and J513 functional requirements.
