3/4" Female Coupler MNPT Cam Lever

The Banjo 75B3/4 is a precision-molded polypropylene coupling designed for spray boom systems on fertilizer application equipment. Its fiberglass-reinforced construction provides high strength and toughness for agricultural environments. The Switch-A-Roo design with self-aligning grooves allows fast nozzle changes without tools. This new component connects a 3/4" female coupler to a 3/4" male NPT thread.

300 psi Maximum Operating Pressure Limit

The coupling is rated for a maximum operating pressure of 300 psi, setting a firm boundary for system design. Exceeding this pressure risks seal failure or structural damage to the polypropylene body. EPDM gaskets provide the sealing interface within this pressure range. Installers must verify that the spray system's peak pressure stays at or below this rated limit.

Polypropylene Construction

The fiberglass-reinforced polypropylene body handles standard agricultural fertilizers and chemicals used in spray applications. It resists corrosion that affects metal couplers in similar service. The material is not suited for high-temperature fluids or pressures beyond the 300 psi rating. Buyers needing higher pressure ratings or different chemical resistance should verify compatibility before specifying this coupler.

Questions about this item

Which size should I choose between the 1/2" and 3/4" female coupler versions?

The 3/4" female coupler matches 3/4" male thread pipework directly. The 1/2" version suits smaller boom connections. Pick the size that matches your existing spray boom thread.

What does the 300 psi maximum operating pressure mean when the coupling is installed on a sprayer?

It is the highest continuous pressure the polypropylene body and EPDM gasket can handle without leaking or deforming. Your pump and hose must stay at or below this limit during operation.

How does the cam lever interface work and what does it limit in practice?

The cam lever locks the male adapter into the female coupler with a quarter-turn. It enables rapid nozzle changes but requires hand operation, so it is not suited for remote or automated actuation.
