Boshart Industries, 4" Cast Iron Locking Well Cap

Ensure the safety and security of your well with the robust Boshart 4" Cast Iron Locking Well Cap. Part of Boshart’s WTCC cast iron well cap series, the Boshart WTCC-C04 is designed to fit a 4-inch well casing and is suitable for residential, agricultural, and commercial well systems, providing a watertight seal thanks to its wide gasket that ensures a positive compression seal even on unevenly cut casings. The cap sits on the well casing above the ground and serves as a secure cover. The cap is secured using five bolts, offering reliable protection.

The Boshart WTCC-C04 is a 4-inch cast iron locking well cap, sometimes called a well cover in the field, built for homeowners, contractors, and property managers who need dependable well protection. It uses a wide gasket and five-bolt compression system for a secure seal, includes two large screened air vents and increased clearance for submersible pump cable. The locking feature adds tamper-resistant security; lock not included. Choosing between different types depends on your well setup and protection needs. It is also built to meet strict modern well construction codes.

Featuring two large screened air vents, this cap helps keep insects and small animals out of wells while allowing the ventilation needed for proper system performance. The added clearance for submersible pump cables makes it a practical choice for private well installations where a secure seal, proper venting, and easier pump cable routing all matter.
