Balcrank Vented Fill Cap, 2 in NPT (4520-019)

The Balcrank 4520-019 Vented Fill Cap with 2-Inch NPT Male Connection is a professional-grade bulk oil storage tank accessory designed for compatible Roth double-wall tanks, Balcrank lubrication systems, and industrial fluid storage applications. Featuring a 2-inch NPT male threaded connection and integrated tank ventilation, this fill cap provides a practical solution for closing a tank filling port while allowing the tank to breathe during fluid filling and dispensing operations.

Designed for automotive repair shops, fleet maintenance facilities, dealerships, heavy-equipment service centers, and industrial lubrication operations, the Balcrank 4520-019 helps support proper atmospheric venting in compatible bulk oil and automatic transmission fluid (ATF) storage systems.

During normal fluid dispensing operations, the liquid level inside a storage tank decreases as oil is withdrawn by a pump. A properly selected vented fill cap allows replacement air to enter the tank, helping prevent excessive vacuum buildup that could interfere with fluid dispensing.

Likewise, during tank filling operations, the vented design allows displaced air to escape, helping reduce unwanted pressure accumulation in appropriately vented storage systems.

The 2-inch NPT male threaded connection is designed to fit compatible female-threaded tank bung openings. This makes the Balcrank 4520-019 a useful replacement or installation accessory for supported Roth double-wall oil tanks and other lubrication storage systems with matching connections.

Balcrank lists part 4520-019 among its bulk tank venting accessories, making it a practical component for professional lubrication installations requiring a vented fill opening.

Whether you're replacing a missing or damaged tank cap, maintaining an existing Balcrank/Roth oil storage system, or installing a new bulk lubrication dispensing station, the Balcrank 4520-019 Vented Fill Cap provides a convenient solution for tank closure and ventilation.

Important: The Balcrank 4520-019 is a vented fill cap, not an emergency pressure relief valve or a certified overfill prevention device. Confirm the tank manufacturer's venting requirements, fluid compatibility, and applicable installation standards before use.

Why Is a Vented Fill Cap Important for Bulk Oil Storage Tanks?

A properly configured storage tank requires adequate ventilation during routine filling and fluid withdrawal.

The Balcrank 4520-019 Vented Fill Cap provides a means for air exchange through a compatible tank opening.

Helps Prevent Excessive Vacuum During Dispensing

As a pneumatic piston pump withdraws oil from a storage tank, the internal fluid level decreases.

Without adequate ventilation, negative pressure can develop inside the tank, potentially interfering with fluid flow and pump operation.

A properly sized vent allows air to replace the withdrawn fluid.

Supports Air Displacement During Tank Filling

When oil or ATF is added to a storage tank, the incoming liquid displaces air.

The vented fill cap provides an air exchange path that helps the tank remain properly ventilated during filling operations.

Convenient Tank Bung Connection

The 2-inch NPT male threaded fitting allows installation into a compatible female-threaded tank bung.

This provides a straightforward replacement option for supported lubrication storage systems.

Supports Organized Bulk Lubrication Systems

Using the correctly specified venting accessories helps maintain a properly configured bulk lubricant storage and dispensing installation.

For facilities using centralized oil dispensing equipment, tank venting is an important consideration when designing the complete fluid-handling system.

Compatibility with Roth Double-Wall Tank Systems

The Balcrank 4520-019 can be considered for compatible Roth double-wall oil storage installations with the appropriate threaded bung and ventilation requirements.

Before ordering, verify:

• Tank Model: Confirm the exact Roth or other compatible storage tank model.

• Bung Connection: Verify that the tank has a 2-inch NPT female connection.

• Fluid Application: Confirm compatibility with the stored lubricant or ATF formulation.

• Venting Requirements: Ensure the cap provides suitable normal venting capacity for the tank's filling and dispensing rates.

• Additional Safety Equipment: Confirm whether separate emergency relief or other tank protection devices are required.

Compatibility should be determined by the actual tank specifications, not tank capacity alone.
