Why Use SECO45 Copper Flare Gaskets

Leaky fittings are the bane of customers. These include HVAC, and automotive to mention a few. A leaky fitting on your air conditioner leads to lose of refrigerant along with increased electrical bills not to mention the environmental impact to the ozone. A leaky fitting on your automobile leads to oil drips and stains in your garage, on your driveway, and in the street in front of your house.

Put Aerospace Technology in Your Toolbox

Service and warranty providers for HVAC, hydraulic, pneumatic, automotive, and other applications utilizing 45-degree flare fittings need a reliable solution that eliminates repeat warranty or service calls for the exact same problem. Typical applications utilizing 45 degree flare fittings are LP and Natural Gas, flammable liquids, instrumentation, refrigeration, power steering, HVAC, hydraulic and pneumatic systems.

Since 1969, SECO SEALS has sealed millions of high-pressure 37-degree flare tube fitting connections for aerospace, automotive and marine applications. Now this simple world class aerospace technology is available for 45-degree flare tube fitting connections.

Improve Customer Satisfaction

The one thing that no service or warranty organization needs or wants is a dissatisfied customer. Customer satisfaction leads to the best advertising possible, Word of Mouth.

Improve your customer satisfaction rating by utilizing SECO45 industry leading 45-degree copper flare gasket sealing solution for applications utilizing 45-degree flare tube fittings. The gasket is intended to never fail and never wear out.  Optional “tin” or “silver” plating for SECO45, 45-degree flare gaskets, is available.

SECO45 Patent Application

This is an excerpt from our Patent Application, Docket 205-00010. “Efforts have been made in the past to address leaks by adding gaskets between fittings. And while generally effective, previous efforts to create gaskets leave ample room for improvement. For example, currently known gaskets fail to contemplate improvements to performance that can be achieved by making the gaskets from softer materials that can be hardened upon tightening. Older gasket technology similarly fails to contemplate precise torquing requirements that lead to a desired material transformation that minimizes leak pathways. Finally, older gaskets also fall short by failing to include, along with other inventive features, specific material coatings that further reduce leak pathways.”
