Mr. Gasket Vacuum Connector

Mr. Gasket Vacuum Connectors: Precision Sealing from a Racing Heritage

Mr. Gasket has been a trusted name in performance automotive parts since 1964, when drag racer Joe Hrudka used his own '57 Chevy as a rolling test bed to develop sealing solutions that could withstand the punishment of racing. Using his own '57 Chevy as a rolling test bed, Hrudka quickly established Mr. Gasket as the go-to source for racers with products that sealed perfectly every time and withstood the punishing temperatures and pressures of racing. That same engineering philosophy carries through to every vacuum connector and fitting the brand produces today.

Why Vacuum Connectors Matter

Vacuum connectors are a critical — and often overlooked — component in any engine build or restoration. From distributor vacuum advance circuits and brake booster lines to emissions controls and fuel pressure regulators, the integrity of your engine's vacuum network directly affects performance, drivability, and safety. A failed cap or cracked fitting can cause erratic idle, misfires, or a loss of power-brake assist. That's why the material quality and fitment precision of every vacuum connector matter so much.

Mr. Gasket Vacuum Connector Products

Mr. Gasket's vacuum connector lineup is designed to meet the demands of both street builds and track day prep. Their flagship offering in this category is the Vacuum Cap Assortment (Part #3704) — a 16-piece kit engineered to block off open engine vacuum fittings. The pieces are made from Buna-N rubber, offering more durability and longer life than neoprene or vinyl, especially when exposed to high temperatures. For enthusiasts routing new vacuum plumbing, Mr. Gasket also offers the SSFlex Vacuum Line Kit (Part #3190), a 3-foot length kit that includes high-tech fittings in a 5/32-inch diameter.

For silicone-based vacuum routing — ideal for show builds and performance applications that demand both looks and reliability — Mr. Gasket offers metric silicone hose kits in multiple sizes and colors. These are suitable for use as vacuum line in applications such as carburetor to distributor vacuum advance or fuel pressure regulator connections. They are legal for sale or use on emissions-controlled vehicles, uncontrolled vehicles, and racing-use-only vehicles because they do not affect vehicle emissions.
