Boshart Industries, 10" Premium Watertight Cast Iron Cap With Screened Air Vent

Boshart Industries WTCL-C10 is a premium 10 inch cast iron well cap from Boshart Industries, built for homeowners with private wells, contractor teams, and water system professionals who need durable, secure wellhead protection. Made from cast iron—one of the heavy-duty materials used in well cap construction alongside aluminum—it features a screened air vent and locking design, with added sealing details that help the cap breathe while resisting environmental degradation over time. It provides easy access to the well without interfering with the seal to casing, while also providing access for electrical wiring and conduit connections. A properly sealed well cap helps protect drinking water, and the EPA warns against missing or damaged well caps because floodwaters and vermin can compromise water quality; insects can introduce bacteria, and surface runoff can carry pesticides into an unsealed well casing. A loose cap can also be dislodged by lawn equipment or falling branches, so a secure locking cover matters. Features include a large 4 inch FPT conduit connection, large dome vent cap with 60 mesh stainless steel screen, two lockable accessory ports, two 1 inch FPT ports for field-installed accessories, and a grounding terminal with bonding to the steel casing by 3 set screws to help protect against electrical faults and lightning strikes.

Introducing the Boshart Industries 10" Premium Watertight Cast Iron Cap With Screened Air Vent, a robust and reliable solution for well water safety, secure installation, and code-conscious system protection.

Benefits of Water Safe Practices

• Durable cast iron construction – Heavy-duty protection built for long service life and dependable pressure balance at the wellhead

• Screened vent – Helps keep insects and debris out while allowing ventilation to prevent vacuum issues when properly sealed, reducing entry from surface water, runoff, pesticides, and other contaminants in the dark, damp environment inside a well if left open, including oil from surface spills

• Tamper-resistant locking design – Enhances well security; check the cap from time to time, and inspect well caps annually for cracks and tampering

• Flexible accessory installation options – Makes it easier to replace a damaged cap immediately to help prevent contamination.

• Supports proper grounding and bonding practices – Adds confidence in a complete, code-conscious installation
