That poppet is a restriction, and every restriction upstream of a jet costs pressure.\u003c\/p\u003e\n\u003cp\u003eA flo-thru coupling has no valve. The bore is clear, flow is unrestricted and pressure drop is minimal. The trade-off is that the line drains when you uncouple it.\u003c\/p\u003e\n\u003cp\u003eChoose flo-thru where flow and pressure matter more than convenience — high pressure work, hot solution lines, and any tool already marginal at the jet.

A flow-through coupling has no valve, so the line drains and a live line does it forcefully.\u003c\/li\u003e\n\u003cli\u003eSeal the threaded end as you would any tapered thread. Never put tape or sealant on the coupling face.\u003c\/li\u003e\n\u003cli\u003eKeep the faces clean. Grit carried into a coupling scores the seat, and a scored seat leaks with every new seal you fit.\u003c\/li\u003e\n\u003cli\u003eReplace a coupling that has become stiff. Stiffness is wear, and wear ends in a joint that will not release under pressure.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat does flow-through mean?\u003c\/h3\u003e\n\u003cp\u003eNo internal shut-off valve.
