1-1/4 in. SCH-80 PVC Socket to Male Threaded Tank Connector BulkHead Fitting Kit ASTM D2467

Create a secure and versatile 1-1/4-inch PVC connection through the wall of a tank, reservoir, container, or other liquid-holding vessel with this 247Garden 1-1/4 in. SCH-80 PVC Socket to Male Threaded Tank Connector Fitting Kit.

This kit combines a 1-1/4-inch Schedule 80 PVC female adapter with a 1-1/4-inch Schedule 80 PVC male threaded tank connector. Together, the components provide a convenient bulkhead connection through the tank wall while creating a 1-1/4-inch PVC socket connection on the inside of the tank.

The internal socket allows compatible 1-1/4-inch PVC pipe to be connected directly inside the tank, giving you greater flexibility when designing inlet, outlet, intake, return, and internal distribution plumbing.

How the Fitting Kit Works

The 1-1/4-inch tank connector passes through the tank wall to create the bulkhead connection. The included gaskets seal against the tank wall, while the nut secures the fitting in place.

The female adapter attaches to the tank connector and provides a 1-1/4-inch socket connection. Compatible 1-1/4-inch PVC pipe can then be solvent-welded into the socket.

The resulting configuration provides:

1-1/4 in. PVC Pipe Inside Tank → 1-1/4 in. Socket → Female Adapter → Male NPT Tank Connector → Tank Wall → External NPT Connection

This allows the tank wall penetration to serve as a connection point for both the external plumbing and the internal PVC piping.

Why Have a 1-1/4-Inch PVC Connection Inside the Tank?

A conventional tank connector can provide a threaded connection through the tank wall, but that does not always give you the internal plumbing configuration you need.

The included 1-1/4-inch socket gives you the ability to connect a length of PVC pipe directly inside the tank.

This is useful when the bulkhead fitting needs to be installed at a convenient location on the tank wall, but the actual intake, outlet, or discharge point needs to be farther inside the tank.

For example, you can use the internal PVC pipe to:

• Extend an intake toward the bottom of the tank

• Extend an inlet farther into the reservoir

• Position a discharge point away from the tank wall

• Create an internal return line

• Direct water toward a specific area

• Build an internal distribution system

• Connect to internal elbows, tees, valves, or other PVC fittings

• Create custom intake or suction plumbing

• Connect to an internal manifold or larger plumbing assembly

The socket connection allows you to determine where the internal pipe ends rather than being limited to the location of the tank-wall fitting.

Build Custom PVC Plumbing Inside the Tank

The 1-1/4-inch socket provides a convenient starting point for building custom plumbing inside the tank.

A length of 1-1/4-inch PVC pipe can be solvent-welded into the socket and routed vertically, horizontally, or toward another location inside the tank.

You can then incorporate compatible PVC elbows, tees, couplings, valves, strainers, reducers, and other fittings as required by your system design.

This makes the fitting kit particularly useful for custom tank installations where the internal plumbing needs to be positioned independently from the tank-wall penetration.

Larger 1-1/4-Inch Connection

The 1-1/4-inch size provides a larger plumbing connection than 1/2-inch, 3/4-inch, and 1-inch configurations.

This makes the fitting useful for systems designed around 1-1/4-inch PVC pipe where maintaining the intended pipe size through the tank connection is important.

The appropriate pipe size should always be selected according to the required flow rate, pressure, pump specifications, system design, and application requirements.

Typical Applications

This 1-1/4-inch SCH-80 PVC tank connector fitting kit can be used for compatible plumbing and fluid-handling applications, including:

• Water storage tanks

• Irrigation reservoirs

• Agricultural water systems

• Hydroponic reservoirs

• Aquaponic systems

• Filtration systems

• Pump installations

• Water distribution systems

• Liquid storage containers

• Custom reservoirs

• Equipment tanks

• Internal tank plumbing

Actual application suitability depends on the tank material, liquid being handled, operating pressure, temperature, chemical compatibility, and installation conditions.

Schedule 80 PVC Construction

Schedule 80 PVC features a thicker wall construction than Schedule 40 PVC and is commonly selected for demanding PVC plumbing applications where a robust fitting is required.

The components in this kit are intended for compatible Schedule 80 PVC plumbing applications and are manufactured to the applicable ASTM D2467 fitting standard.

Tank Wall Installation

Install the tank connector through an appropriately sized opening in the tank wall. Position the included gaskets correctly, then install and tighten the nut to secure the connector.

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

After the tank connector is secured, install the female adapter onto the threaded connection. The internal socket can then be connected to compatible 1-1/4-inch PVC pipe.

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

Support the Connected Plumbing

The tank connector provides the connection through the tank wall, but it should not be used as the only structural support for long, heavy, or mechanically loaded pipe assemblies.

If the installation includes long pipe runs, pumps, filters, valves, or other heavy components, provide appropriate pipe supports. Proper support helps reduce mechanical stress on the tank wall and bulkhead fitting.

A Flexible Solution for Custom Tank Plumbing

The key advantage of this kit is the combination of a threaded tank-wall bulkhead connection and a 1-1/4-inch PVC socket connection inside the tank.

Instead of ending the plumbing at the tank wall, you can extend compatible 1-1/4-inch PVC pipe into the tank and create an internal plumbing system tailored to your application.

Whether you need to extend an intake, position a discharge point, create a return line, or build an internal distribution system, the 1-1/4-inch socket provides a convenient connection point for standard PVC pipe.
