Flame-arresting vent caps prevent external ignition from reaching flooded lead-acid battery cells. Easy twist-on installation, quick removal for watering. Essential for RVs, boats, and trailers.
The Flow-Rite BA-VNT-005-24 Flame-Arresting Vent Cap brings together simplicity, efficiency, and safety into a single practical and cost-effective product. These professional-grade vent caps feature integrated flame arrestors that prevent external fires and sparks from entering the battery case where they can ignite internal gases.
Made in the USA, these vent caps were engineered for unprecedented safety and thoroughly tested for flame and spark by independent battery laboratory JBI Corporation. The low-profile design ensures maximum clearance even when batteries are installed with reduced overhead access, making them perfect for enclosed or mobile environments like RVs, boats, and trailers.
This 24-pack provides excellent value for RV owners, marine applications, or anyone maintaining multiple battery systems. The durable polymer construction with quarter-turn bayonet lug installation allows for quick removal when watering is needed, then reinstalls just as easily to maintain continuous protection.
