This unloader is one of the most common replacements on most triplex pumps up to 7.8 GPM
and 4000 PSI. The inlet is 3/8" FPT, and the outlet is 3/8" FPT. This is a "dual bypass"
style, which means your 3/8" bypass hose can connect to either side of this unloader.
If you have a typical triplex pump and your pressure washer puts out no more than
4000 PSI and 7.8 GPM, this unloader is probably what you want.
This unloader is not what you want if your current unloader is a "banjo" or
"bolt on" style where one piece bolts on to both the high and low side of
your pump.
This unloader threads into the high pressure side threaded opening.
This is the exact unloader used on most Pressure Pro models below 8 GPM and all cold
water Black Knight machines.
Anybody can replace an unloader when they make it this easy!
