Machined to precise dimensions—56mm internal insert, 79.5mm outer diameter, and an 18mm engagement depth—the 7030 reduces fluid loss and maintains system pressure so technicians can perform efficient brake service. It pairs with a 1\/2\" Nitto quick-connect, using 1\/8\" BSP threads, making it compatible with most shop bleeder hoses and fittings.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles and reservoir types does the CTA 7030 fit?\u003c\/h3\u003e\n\u003cp\u003eThe 7030 is intended for Honda and Acura models that use a 56mm-style reservoir opening. Common fitments include Accord, Civic, CR-V, HR-V, Odyssey, Pilot, Ridgeline, and select Acura models such as RL, Legend, and NSX. Because Honda\/Acura used several cap and tank designs across years, always check the reservoir diameter before ordering.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFits reservoirs with a 56mm internal opening and 18mm engagement depth\u003c\/li\u003e\n  \u003cli\u003eCommon in multiple Honda and Acura models across different production years\u003c\/li\u003e\n  \u003cli\u003eWorks with plastic and composite reservoir necks designed to the same OEM profile\u003c\/li\u003e\n  \u003cli\u003eNot suitable if reservoir measures 55mm — use CTA 7033 in that case\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the adapter connect to a pressure-bleeder system?\u003c\/h3\u003e\n\u003cp\u003eThe 7030 includes a professional 1\/2\" Nitto quick-connect with 1\/8\" BSP threads for a secure, shop-standard link to pressure-bleeder units.
