In a realm where safety, innovation, and professionalism reign supreme, our DuraVent 3"-8" Aluminum Gas Vent Storm Collar stands as a testament to our unwavering commitment to excellence. At DuraVent, we've established ourselves as the vanguard of the venting industry, offering a diverse range of top-tier engineered products tailored to meet the unique demands of the HVAC and Hearth markets.

Our Type B Gas Vent system, featuring the groundbreaking DuraLock technology, revolutionizes the way you connect and secure your venting components. Experience the satisfaction of perfect alignment as the indicators meet, feel the sturdy connection as the ends join seamlessly, and hear the reassuring snap as your connection firmly locks into place. The result? A leak-proof and resilient venting solution that guarantees the safety and efficiency of your gas appliances.

Designed to thrive in the rugged conditions of job sites, our Type B Gas Vent boasts a recessed inner wall that eliminates the risk of damage during handling. This durability is complemented by rapid heating capabilities, ensuring minimal condensation in both your appliance and vent system throughout operation. With pipe lengths ranging from 6 to 60 inches and a comprehensive selection of adjustable and rigid fittings, DuraVent empowers you to customize your venting setup with unmatched ease and precision.

However, it's essential to note that while our Type B Gas Vent is a pinnacle of performance, it is not suitable for wood-burning or coal applications, industrial ovens, exhaust ranges and hoods, grease or pollution ducting, or as free-standing exhaust vents for high-temperature environments.
