The UltraLife-Disc Characteristics
- Full Immersion E-coating
Full immersion electro-deposition coating inside and out and an exclusive powder coating finish for the most durable corrosion protection in the industry. - Unique Port Adapter
UL-Disc features a unique composite port adapter which reduces profile size and allows for easy air connection. - Patented Bushing Assembly
Patented bushing assembly provides center seal that traps lubricant for extended service, reducing center section leaks and brake drag. - Premium Diaphragm
Premium diaphragms feature high quality contaminant resistant rubber reinforced with nylon fabric tested well beyond the toughest industry specifications. - All Steel Design
All steel design provides durable, air tight center section that virtually eliminates leaks, structural failures and prevents galvanic corrosion. - High Vibration Base
TSE designed High Vibration "HV" mounting base reduces vibration for longer life standard on UltraLife products. - Innovative Design
UL-Disc features a 100% steel inverted spring bottom housing that reduces both spring coil-to-coil contact and spring coil-to-spring housing contact. The all-steel design provides a durable, air-tight center section that virtually eliminates leaks and structural failures, while the recessed pressure plate allows for a shorter and more compact chamber. - Premium Quality
TSE is an ISO 9001 and KBA certified company. As an OEM premium direct fit and aftermarket replacement, UL-Disc is the premium brake for your heavy-duty disc brake trucking application. - Tough Main Spring
UltraLife main spring adds a proprietary base coating in addition to TSE's multi-stage coating system for the ultimate in corrosion protection. Tested to double SAE standards, UL-Disc’s main spring actually exceeds SAE dry cycle testing requirements in a slurry environment. - Complete In-House Testing
UL-Disc brake actuators undergo rigorous in-house testing in TSE’s comprehensive testing lab. Tests include variable pressure cycle testing, vibration testing, hot cell cycle testing, salt spray testing, cold cell leak/operational testing and slurry testing - Superior Corrosion Resistance
With TSE’s exclusive in-house process, all parts of the UL-Disc actuator receive a multi-stage pre-treatment prior to e-coat and an extra layer of polyester powder coating protection.
