Transportation Industry (Bus Sector) — Connectall LTD
Serving the Bus and Coach Market
Connectall LTD is a trusted Canadian supplier of silicone and PTFE hose assemblies serving the bus and transportation industry. Our engineered solutions support transit buses, school buses, intercity coaches, and shuttle fleets across North America. We help OEMs and fleet operators improve reliability, uptime, and thermal efficiency through advanced silicone heater and coolant hoses, turbo and charge-air hoses, PTFE stainless-steel braided hoses, and hydraulic assemblies.
Industry Overview and Market Drivers
The bus manufacturing and maintenance industry is evolving rapidly due to:
Electrification and battery-electric vehicle (BEV) adoption
Extended vehicle lifecycles and total cost-of-ownership optimization
Stricter emission and cooling system standards
Continuous operation demands under harsh thermal and vibration conditions
Connectall’s silicone hose technology and PTFE fluid transfer systems are designed to outperform conventional rubber hoses in these demanding applications.
Product Solutions for the Bus Industry
1. Silicone Heater and Coolant Hoses
Our silicone heater and coolant hoses for buses deliver reliable performance in high-temperature and high-vibration environments. Ideal for:
Diesel, hybrid, and electric bus cooling loops
E-heaters, DC/DC converters, inverters, and charger cooling circuits
Battery pack thermal management systems
Key benefits include extreme temperature resistance, long service life, and compatibility with modern coolants and dielectric fluids.
2. Silicone Turbo and Charge-Air Hoses
Connectall’s silicone turbo hoses and charge-air cooler (CAC) hoses handle elevated pressures and temperatures typical in turbocharged diesel engines. Reinforced multi-ply silicone constructions maintain flexibility and performance, even under constant thermal cycling. Optional fluorosilicone liners resist oil mist and chemical degradation.
3. PTFE Stainless-Steel Braided Hoses
Our PTFE stainless-steel braided hoses are engineered for fluid transfer and hydraulic lines where temperature, pressure, and chemical resistance are critical. Common uses include:
Transmission and steering systems
Hydraulic actuation (kneeling, braking, or lift systems)
Chemical and coolant transfer lines in hybrid and BEV buses
These assemblies offer minimal permeation, low volumetric expansion, and excellent fatigue resistance.
4. Hydraulics and Power Systems
Connectall supplies complete hydraulic hose assemblies for bus steering, suspension, and door systems. Our hydraulic solutions feature high impulse resistance, abrasion protection, and reliable fittings to reduce maintenance downtime.
5. Silicone for Battery Cells
As fleets electrify, Connectall supports EV bus battery manufacturing with silicone compounds for potting, sealing, gap filling, and thermal interface materials. These materials provide vibration damping, electrical insulation, and consistent thermal management for battery modules.
