Product information

Description

Flange blanking cap for enameled vertical tanks 250–500 L with 6/4” heater opening — KOSPEL is a sealing component intended for use with KOSPEL-compatible enameled vertical hot-water storage tanks. It closes the flange opening normally used for inserting a heating element, preventing water leaks and protecting the tank interior from dust and contaminants when the heater is not installed or during maintenance and replacement work.

Advantages

The flange blanking cap provides a tight seal at the heater flange to reduce the risk of leakage and corrosion around the opening. Manufactured to match the dimensions of tanks with a 6/4” heater opening, it enables safe temporary or permanent closure without modifying the tank. The design facilitates straightforward installation and removal, and the cap resists common conditions inside hot-water storage systems to maintain tank cleanliness and integrity.

Suitable for

  • Sealing the heater flange on enameled vertical hot-water tanks with capacities between 250 and 500 liters
  • Maintenance periods when the heating element is removed
  • Replacement or storage of tanks without a heater installed
  • Domestic and commercial hot-water storage systems requiring flange closure

Key specifications

  • Compatibility: enameled vertical storage tanks with 250–500 L capacity and 6/4” heater opening
  • Function: flange blanking/sealing for heater opening
  • Material characteristics: suitable for contact with internal tank environments and resistant to moisture (specific material may vary by manufacturer)
  • Mounting: fits standard flange dimensions for 6/4” heater ports on compatible tanks

How to use

Before installation, ensure the tank is drained or the flange area is dry and clean. Align the blanking cap with the heater flange opening and secure it according to the cap's mounting method (threaded or bolted depending on design). Tighten uniformly to form a leak-proof seal without over-torquing to avoid damaging the flange or cap. For removal, loosen fastenings evenly and withdraw the cap, inspecting the sealing surface and sealing element for wear before re-use or replacement.

Usage recommendations

Regularly inspect the sealing surface and gasket (if present) for signs of wear, deformation or mineral buildup, and replace the blanking cap or gasket if integrity is compromised. When used during maintenance, follow safe draining and isolation procedures for the tank and observe manufacturer guidance for torque and fastening methods to preserve flange condition.
