Water-Tite 81590 Adjustable Type B Vent Storm Collar
The Water-Tite 81590 is built for 6-inch vent pipes and uses 28-gauge G-90 ASTM-A653 galvanized steel. An adjustable slip tab allows a snug fit around the vent, while a locking tab secures the installation to resist wind uplift and weathering. This model emphasizes straightforward installation with a durable metal finish designed for roof penetration sites where a reliable seal matters most. Its galvanization helps resist corrosion in typical attic and rooftop environments. Consider fit precision and compatibility with your vent stack diameter when selecting this collar.
Water-Tite 81591 Adjustable Type B Vent Storm Collar
Designed for larger vent stacks, the Water-Tite 81591 fits 7-9″ pipes. It employs the same 28-gauge G-90 galvanized steel with an adjustable slip tab and locking tab for a secure seal. This collar is suitable for roofs with broader vent penetrations or where a more robust collar is desirable to accommodate slight misalignments during installation. The stamped finish and durable construction aim to provide long-term performance in exterior conditions common to American homes.
United States HDW/U S HA Galvanized Storm Collar, 8″
The Imperial 8-inch galvanized storm collar is presented as a good-quality option for standard 8-inch vent penetrations. It provides a corrosion-resistant finish and is suitable for traditional roof flashing setups. While it is not as feature-rich as some adjustable models, its straightforward design offers reliable performance in steady weather zones. Manufacturing and sourcing notes indicate a practical balance between cost and durability for typical residential applications.
Water-Tite 81602 Stamped Type B Vent Storm Collar
The Water-Tite 81602 is a stamped Type B storm collar designed for 6-inch pipes, offering a waterproof seal where the stack passes through the roof. It installs directly above flashing, which can streamline roof-penetration sealing in many installations. The 28-gauge G-90 galvanized steel construction provides durability against wind-driven rain and freeze-thaw cycles. Installation strategy focuses on precise alignment with the vent stack and correct flashing integration to maximize weatherproof performance.
Water-Tite 81589 Adjustable Type B Vent Storm Collar
The 81589 model fits 5-inch vent pipes and includes the familiar adjustable slip tab along with a locking tab for added installation security. Made from 28-gauge galvanized steel, this collar provides a reliable seal over typical 5-inch stacks and is well-suited for smaller vent penetrations where space around the flashing is limited. As with other Water-Tite products, compatibility with existing flashings and roof materials should be verified before installation.
Water-Tite 81598 Stamped Type B Vent Storm Collar
The 81598 stamped collar is designed for 4-inch pipes and emphasizes a waterproof seal where the stack passes through the roof, installed and sealed directly above the flashing. This model is compact and cost-effective for smaller vent penetrations while maintaining a robust weatherproof barrier. Ensure that the chosen collar matches the vent diameter and roof flashing configuration for proper sealing and longevity.
Buying Guide: Storm Collars For Vent Pipes
Key factors to consider when selecting a storm collar include pipe size compatibility, material quality, and installation method. For outdoor exposure, galvanized steel with a G-90 coating provides corrosion resistance best suited to northern and coastal climates. Adjustable collars offer flexibility when vent sizes vary or precise fit is needed, while stamped or stamped-and-sealed designs emphasize waterproof performance above the flashing. Consider the roof type and flashings in your area, along with wind uplift and snow load expectations. Safety and ease of installation should align with your DIY skills or professional contractor capabilities.
Fit range considerations:
– Match the collar to the vent pipe diameter to avoid gaps or compression.
– Check if the roof requires a single-piece seal above flashing or a two-piece approach for complex flashing.
– For larger stacks, select collars with wider ranges or adjustable tabs to ensure a secure hold.
Material and durability:
– 28-gauge galvanized steel with G-90 coating balances strength and corrosion resistance for most residential roofs.
– Stamped or stamped-and-sealed collars may offer enhanced waterproof sealing at critical roof penetrations.
– Avoid cheaper or non-galvanized options in areas with heavy precipitation or salt exposure.
Installation tips:
– Clean and dry the vent pipe and roof surface before applying any sealant or hardware.
– Align the collar accurately with the vent to minimize water entry points.
– Use the locking tab to secure the collar after achieving a snug fit, ensuring the installation remains stable under wind loads.
