Brake Bleeder Adapter 28-70mm Universal Reservoir Cap

A universal brake bleeder adapter used to connect pressure bleeding equipment to brake fluid reservoirs with the correct collar arrangement on the filler cap. The adjustable 28-70mm fitting range makes it a practical option when one brake bleeder adapter needs to cover different vehicles rather than keeping separate caps for each one.

Used for brake servicing in garages, in workshops and at home, this brake reservoir adapter helps when carrying out brake fluid changes or bleeding work across mixed vehicle applications. It suits buyers who work on more than one vehicle and want a flexible pressure bleeding setup for regular vehicle maintenance without overcomplicating the job.

The adjustable design covers diameters from 28mm to 70mm, so it can suit many common reservoir cap sizes where a collar is present. It holds pressure up to 3.5 bar, also listed as 50 psi, which is useful when a steady seal is needed during bleeding. For repeat servicing work, having one adjustable adapter close to hand can help avoid switching between multiple fixed-size fittings. That makes it easier to keep brake maintenance straightforward, especially in busy workshop use or when servicing different cars at home.
