It includes two interchangeable sealing cones and an adjustable mechanism so you can match a range of reservoir diameters. Built from brake-fluid–resistant materials, the adapter is intended for routine maintenance in DIY garages and professional shops — but it must only be used on compatible round openings to achieve a proper seal.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I confirm this adapter fits my reservoir?\u003c\/h3\u003e\n\u003cp\u003eCheck the shape and diameter of your master cylinder reservoir before ordering: the Saillong adapter is made specifically for round openings.

Never pressurize the system before verifying the adapter is securely seated and the connections are aligned; also avoid using the adapter on incompatible reservoir shapes.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDo not use on oval, square, or irregular reservoir openings.\u003c\/li\u003e\n  \u003cli\u003eAlways confirm the adapter and bleeder hose connections before applying pressure.\u003c\/li\u003e\n  \u003cli\u003eReplace worn sealing cones to maintain leak-free operation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: The Saillong Brake Bleeder Adapter is aimed at home mechanics, professional technicians, and fleet serviceers who use pressure-type brake bleeder systems and need an adjustable, durable master cylinder cap for round reservoirs. If you routinely perform brake fluid changes, own vehicles with standard round reservoirs, and want a reusable, leak-resistant connection for pressure bleeding, this adapter is designed to make the job cleaner and more efficient. If your vehicle has a non-round or unusual master cylinder opening, consult fitment guides or contact support before purchasing.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use this adapter on non-round master cylinder openings?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No — the adapter is designed for round reservoir openings only and will not seal properly on oval, square, or irregular shapes.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Are replacement sealing cones available?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The kit includes two cones; contact Saillong support for replacement cones or guidance on sourcing compatible seals.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Saillong","offers":[{"title":"Default Title","offer_id":55168336888151,"sku":"B0GWZGPDQ8","price":57.41,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/saillong-front-view-adapter-mounted.jpg?v=1790400823","url":"https:\/\/britishgarage.co.uk\/products\/saillong-brake-bleeder-adapter-universal-round-reservoir-cap-adjustable-leak-resistant-seal","provider":"British Garage","version":"1.0","type":"link"}
