3/4 in. SCH-80 PVC Socket to Male Threaded Tank Connector Bulkhead Fitting Kit ASTM D2467

Create a secure and versatile 3/4-inch PVC connection through the wall of a tank, reservoir, container, or other liquid-holding vessel with this 247Garden 3/4 in. SCH-80 PVC Socket to Male Threaded Tank Connector Pipe Fitting Kit.

This kit combines a 3/4-inch Schedule 80 PVC female adapter with a 3/4-inch Schedule 80 PVC male threaded tank connector. The combination creates a convenient bulkhead connection through the tank wall while providing a 3/4-inch PVC socket connection on the inside of the tank.

The internal socket is especially useful when you need to extend PVC pipe into the tank, position an inlet or outlet at a specific location, or build additional plumbing inside the tank.

How the Fitting Kit Works

The 3/4-inch tank connector passes through the tank wall and creates the bulkhead connection. The included gaskets seal against the tank wall while the nut secures the connector in position.

The female adapter attaches to the tank connector and provides a 3/4-inch socket connection. Standard 3/4-inch PVC pipe can then be solvent-welded into the socket.

This gives you a practical plumbing transition:

3/4 in. PVC Pipe Inside Tank → 3/4 in. Socket → Female Adapter → Male NPT Tank Connector → Tank Wall → External NPT Connection

This configuration allows the plumbing to continue inside the tank rather than ending at the tank wall.

Why Is the Internal 3/4-Inch Socket Useful?

A standard tank connector can provide a threaded connection through the tank wall, but many tank plumbing applications require the pipe to extend farther inside the tank.

The 3/4-inch socket included in this kit makes that possible.

You can connect a section of 3/4-inch PVC pipe directly to the internal socket and extend the pipe to the desired location.

For example, the internal PVC pipe can be used to:

• Extend an inlet deeper into the tank

• Move an outlet away from the tank wall

• Position an intake closer to the bottom of the tank

• Create an internal water return line

• Build an internal distribution system

• Connect to an internal manifold

• Direct water toward a specific area

• Create custom suction or discharge plumbing

This is particularly useful when the tank wall penetration and the desired pipe location are not at the same point.

Build Custom Plumbing Inside the Tank

The socket connection gives you more freedom when designing the internal plumbing.

For example, if the tank connector is installed several inches above the bottom of the tank, you can solvent-weld a length of 3/4-inch PVC pipe into the internal socket and extend it downward.

The same connection can also be used to create horizontal plumbing, vertical plumbing, elbows, tees, valves, strainers, or other compatible PVC assemblies inside the tank.

This allows the bulkhead fitting to function as part of a larger plumbing system rather than simply acting as a pass-through connection.

Typical Applications

The 3/4-inch SCH-80 PVC tank connector kit is suitable for many custom plumbing and fluid-handling applications, including:

• Water storage tanks

• Irrigation reservoirs

• Hydroponic systems

• Aquaponic systems

• Agricultural water systems

• Filtration systems

• Pump installations

• Water distribution systems

• Liquid storage containers

• Custom reservoirs

• Equipment tanks

• Internal tank plumbing

The actual suitability depends on the tank construction, liquid being handled, temperature, pressure, chemical compatibility, and installation conditions.

Schedule 80 PVC Construction

Schedule 80 PVC provides a thicker wall construction than Schedule 40 PVC and is commonly used where a more robust PVC plumbing component is desired.

The fittings in this kit are designed for compatible Schedule 80 PVC plumbing applications and are manufactured to the ASTM D2467 standard applicable to the listed PVC fittings.

Tank Wall Installation

To install the tank connector, drill the appropriate hole through the tank wall for the bulkhead fitting. Position the connector and gaskets correctly, then install and tighten the included nut to secure the fitting.

Do not overtighten the nut. Excessive force can deform the gasket, damage the tank wall, or affect the seal.

After securing the tank connector, install the female adapter onto the threaded connection. The internal socket can then accept compatible 3/4-inch PVC pipe.

Use an appropriate PVC primer and solvent cement system according to the pipe and fitting manufacturer's instructions.

Support Internal and External Plumbing

Although the tank connector creates the connection through the tank wall, it should not be used as the sole structural support for heavy or unsupported piping.

If the system includes long pipe runs, valves, pumps, filters, or other heavy components, provide appropriate pipe supports. This helps reduce mechanical stress on the tank wall and bulkhead connection.

A Flexible Solution for Tank Plumbing

The main advantage of this fitting kit is the combination of a threaded tank-wall connection and a 3/4-inch socket connection on the inside.

Instead of having only a threaded connection at the tank wall, you can extend standard 3/4-inch PVC pipe into the tank and build the internal plumbing around the actual requirements of your system.

Whether you need to extend an intake, position a discharge point, create a return line, or build an internal distribution system, the socket connection provides a simple way to connect standard PVC pipe directly inside the tank.
