It connects to a shop air source and works with lightweight flushing solvents (not included) to purge lines, helping reduce contamination risks during repairs or retrofits.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the pressure regulation and safety relief work?\u003c\/h3\u003e\n\u003cp\u003eThe kit includes an adjustable pressure relief valve to set a safe working limit and an automatic vent if pressure climbs too high. Use a hex key to fine-tune the valve; the built-in safeguard opens above roughly 170 psi to protect components. Keep recommended working pressure under 150 psi for routine flushing tasks.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable relief valve — tighten\/loosen with a hex wrench to change setpoint\u003c\/li\u003e\n  \u003cli\u003eAutomatic vent above ~170 psi for overpressure protection\u003c\/li\u003e\n  \u003cli\u003eRecommended working cap: do not exceed 150 psi in normal use\u003c\/li\u003e\n  \u003cli\u003eClear gauge lets you monitor bottle pressure in real time\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat parts come with the kit and how are they built for durability?\u003c\/h3\u003e\n\u003cp\u003eEvery kit ships with a thickened stainless-steel canister, a corrosion-resistant spray head, a steel draft tube, fittings and a 3.5 ft high-pressure hose.
