LVOUP Vacuum Reserve Canister — 5" x 7" Steel Black, 1/8" NPT Ports & Check Valve for Stable Brake Vacuum

The LVOUP Vacuum Reserve Canister is a 5-inch diameter by 7-inch long steel reservoir that stores extra vacuum for consistent power-brake performance in high-demand engines.

This compact, powder-coated steel canister helps stabilize vacuum supply where the engine’s own vacuum may dip—such as on big-cam, high-performance, or turbocharged applications—by providing a small reserve that smooths brake response. Designed with multiple 1/8" NPT ports and a one-way check valve included, the unit is built for straightforward integration near the brake booster or vacuum source.

How does the canister improve brake feel under heavy engine loads?

When engine vacuum falls during heavy throttle or large-cam operation, the reserve canister supplies stored vacuum so the brake booster still receives adequate suction. This reduces pedal fade and helps maintain consistent braking force.

• Stores vacuum to smooth temporary drops in engine vacuum
• Includes a one-way 3/8" barb check valve to retain vacuum in the reservoir
• Connects directly to vacuum source near the brake booster for quickest response

What fittings and installation options are available with this LVOUP canister?

The canister features 1/8" NPT threaded holes for fittings, a pressure gauge, or a port plug, letting you customize plumbing and monitoring. The package includes a 90-degree 1/8" NPT fitting, a port plug, grommet, handle and hardware for secure mounting, and the one-way check valve for correct flow control.

• 1/8" NPT x 90-degree fitting and port plug included
• Grommet for sealed hose routing and handle with mounting hardware
• One-way 3/8" barb check valve to prevent vacuum loss back to the engine

What materials and durability features does the canister offer?

Constructed from sturdy steel with a black powder-coated finish, the canister resists distortion and corrosion for long-term service under the hood. Its compact shape and powder coat make it suitable for visible mounting locations while helping protect against environmental wear.

• Steel body resists bending and maintains shape under pressure
• Black powder-coated surface for corrosion resistance and clean appearance
• Compact 5" x 7" size fits tight engine bays without sacrificing capacity

How should I connect and maintain the vacuum reserve canister?

Mount the canister near the vacuum source—typically close to the brake booster—using the included hardware and route vacuum lines through the provided grommet. Use the check valve to keep vacuum stored; inspect fittings and hoses periodically for tightness and replace any worn lines to maintain dependable performance.

• Install on a solid bracket using supplied handle and hardware
• Use the grommet for clean hose entry and the included fittings for tight connections
• Perform periodic checks on hoses, fittings, and the check valve for leaks or wear

Who is this for: The LVOUP Vacuum Reserve Canister is aimed at automotive enthusiasts, professional mechanics, and anyone upgrading brake systems on high-performance street or race engines where vacuum can fluctuate. It’s also useful for older vehicles with weak vacuum sources and for custom builds that require a compact, durable vacuum reservoir. Note: confirm compatibility with your vehicle before purchase and consider professional installation if you are unfamiliar with brake or vacuum plumbing.
