Why Sealco Should Be Your Valve And/Or Harness Supplier?

Quality – Sealco valves are produced to the highest standards using a special zinc alloy that reduces porosity & results in stronger threaded ports. All air valves are 100% pneumatically & submersion tested for zero leakage before shipment to our customers. Our harness systems are produced with quality materials using state of the art stripping, molding, and ultrasonic welding machinery.

Price – Sealco is consistently the lowest cost producer of trailer air brake valves & related components in North America.

Selection – Sealco offers the largest selection of air brake valves to the commercial trailer manufacturer. We are the only supplier to offer all three types of spring brake control valve priorities in a stand alone valve. If you have a need for a custom air valve product, our Engineering & Production teams will work with you to create it.

Availability – Sealco’s warehouses are strategically located in both Indiana & Arizona to serve the trailer industry. We maintain a full inventory of Sealco products & Meritor WABCO ABS components at both of these locations & take pride in the fact that 97% of the products ordered ship within 48 hours of receipt of order.

Made In The U.S.A. – All Sealco products are designed, engineered, manufactured & assembled in the U.S.A. You never need to worry about the quality of foreign parts or assembly & you can be proud to support our American workers.

ABS Experience – Sealco is the only company in North America that is directly authorized by Meritor WABCO to sell & service their ABS systems to trailer OEMs. Our successful involvement with ABS systems since 1996 has made us a leader in spec’ing, installing & trouble shooting complete air brake systems.

Servicability – Sealco products often contain plug units that allow the fleet customer to replace only a portion of a valve instead of the entire valve thereby saving time & money. Repair kits are also available for other portions of the valve.

Representatives – Sealco employs ten Regional Managers throughout North America who have been with us an average of 15 years & in the heavy-duty commercial vehicle industry an average of 24 years. They are dedicated to our customer’s complete satisfaction.

Technical Expertise – Sealco’s Regional Managers & in-house technicians make up the finest air brake technical team in the industry today. They can assist in the design & spec’ing of the most complicated air brake systems & provide technical assistance over the phone or in the field to dealers, distributors or fleet customers.

Integration – Sealco valves are produced in our own die cast & machine shop facilities which means we control our product at every stage of the manufacturing process. This assures consistent quality & a no excuses delivery policy.

People – In the end, it’s the Sealco people who make it all work. We strive to have every employee understand that the only job security we have is a satisfied customer. Orders are taken, products are shipped, problems are handled & issues are resolved. This is the kind of service our customers have come to expect & it’s what we deliver.


The strong TSE Brakes, Inc. that you see today is the culmination of 40 years of progress in spring brake innovation. The company’s origin dates back to the early 1960’s, when the Smith family started out as young, determined remanufacturers of spring brake chambers. In 1970, TSE developed its own new design based on experience gained through many years of remanufacturing and testing. TSE created the Omnibrake family of completely new units that changed the industry. Today, TSE no longer remanufactures, as its focus has shifted to the OEM market. . In recent years, TSE has added one of the most extensive lines of disk brake actuators in the industry. As the standard equipment choice among a growing list of new truck and trailer manufacturers worldwide, the popularity of TSE’s Omnibrake has taken off, generating record sales.

The company has grown over the years because of its approach to research and development. This innovative approach began by taking apart over three million of the competition’s failed spring brake chambers that had been returned to TSE as cores and examining their failures. From this data, TSE’s Engineering Team has built into the Omnibrake a long list of patented innovations to reduce or eliminate nearly all of the serious causes of premature brake chamber failure. Today, TSE’s R&D consists of a rigorous program of lab and field testing.

The greatest result of TSE’s commitment to R&D was the creation of a true “double life” unit built to deliver years of reliable service. The Omnibrake’s major components all enjoy service life cycles that far exceed the recommendations of the Society of Automotive Engineers, or SAE.

In tough SAE salt spray testing, the Omnibrake’s exclusive electrodeposition coating delivered 1,000 hours of protection, greatly surpassing the SAE’s recommendation of only 96 hours. The unit’s rubber diaphragms easily cycle over two million times, more than double the SAE’s one million cycle recommendation. And where the SAE says a spring brake chamber’s main power spring should last a recommended 200,000 cycles, TSE’s Omnibrake consistently tests out at over 500,000 cycles.

The TSE Brakes of today is a much larger operation than in those first few years. With over 350 employees, a chain of warehouses across North America, and it’s own private fleet of company over-the-road trucks, TSE has blossomed into a contender in the worldwide spring brake marketplace. Due to its focus on stringent quality controls, TSE Brakes is certified as QS 9000 and ISO 9001 compliant. Meeting these high worldwide quality standards means that TSE can become standard equipment on major power equipment manufacturers both in the U.S. and abroad.

Along with Chairman of the Board and Founder Ted Smith, his son Greg Smith and son-in-law, Steve Lum get involved in the day-to-day task of supplying new spring brakes to more than 30 countries around the globe. Greg is President and Steve is Vice President – Finance. TSE enjoys a stable workforce made up of reliable people, many of which have been with TSE for more than 30 years.
