Overview

The Holman 90mm Threaded Access Coupling joins two lengths of 90mm stormwater pipe while providing a threaded access point in the line. It is the fitting to use where a drain needs to be inspectable or rodable at a set point, because the threaded outlet can be opened without cutting the pipe run.

It is made from quality recycled PVC and used for stormwater and rainwater drainage. The coupling is solvent welded into place and complies with AS/NZS 1254 for stormwater fittings.

Key Features

• 90mm stormwater coupling with a threaded access outlet
• Joins two lengths of 90mm pipe in one fitting
• Threaded access point for inspection and rodding
• Made from quality recycled PVC
• Solvent weld connection for a watertight joint
• Complies with AS/NZS 1254, AMI 70007

Specifications

• Size: 90mm nominal
• Connection: solvent weld, female sockets
• Access: threaded outlet
• Material: recycled PVC
• Application: stormwater and rainwater drainage
• Standard: AS/NZS 1254, AMI 70007

Applications

• Joining a 90mm stormwater pipe run
• Providing a clean-out point in a drainage line
• Inspection access on a buried stormwater pipe
• Above and below ground stormwater systems

What You Need to Complete the Job

Cut the pipe ends square, dry-fit the coupling, then solvent weld both sockets. Use the threaded outlet with a matching cap or plug, and open it only when the drain needs inspection or rodding. Use it with the 90mm stormwater pipe and cement with Bostik Pipe Cement Type N. More fittings are in the PVC Fittings range.

Frequently Asked Questions

What is a threaded access coupling used for?

It joins two pipe ends and provides a threaded access point in the line. The threaded outlet takes a cap or plug, and opening it gives access for rodding, flushing or inspecting the drain without cutting the pipe run.

Where should I fit one in a drainage system?

Fit it at points where the drain may need access, such as at a change of direction, at the start of a long run, or where a branch comes in. A capped access coupling at these points makes future maintenance much easier.

Can I use this as a standard coupling?

Yes. It joins two lengths of 90mm pipe exactly like a standard coupling, with the threaded access as an added feature. If you do not need the access, keep the threaded outlet capped and the fitting works as a plain joint.

Is it suitable for buried pipe runs?

Yes. The recycled PVC coupling is made for above and below ground stormwater work, and the solvent weld joints give permanent watertight connections. Record the location of access points on buried runs so they can be found later.
