DIYers and aquarium enthusiasts, this PVC bulkhead fitting is built tough for serious projects! The 1-inch female NPT threads work with standard plumbing connections for rain barrels, water tanks, aquariums, and ponds. Made from high-quality virgin PVC that's corrosion-resistant and non-toxic - no heavy additives that could contaminate your water. The whopping 4mm thick silicon seal gasket ensures a watertight connection that won't leak over time. Rated for temperatures from 40 to 140°F and maximum pressure of 150 PSI, this fitting can handle demanding applications. The oversized locking nut provides extra security compared to standard plastic fittings. You'll need to drill a 1 3/4-inch hole for installation, and while it's threaded from the front end, it can be installed on the back end if needed. Weighing just 2.9 ounces, it's lightweight yet incredibly durable. Perfect for commercial and industrial use, but also great for home rainwater collection systems, aquaponics, or custom aquarium setups. The gray color blends well with most systems. If you're tired of cheap fittings that leak or break, this PRO Series bulkhead delivers professional quality that'll last for years. Your water system will thank you for choosing such a reliable component!
