Philmac Large Bore Fittings

The Philmac Large Bore Metric compression fitting is made from advanced thermoplastic materials providing a high degree of corrosion and UV resistance. The material is also lightweight and is completely non-toxic and taint free. Rated to 16 Bar and providing a greater than 50 year design life, Philmac’s Large Bore Metric compression fitting is designed to handle the most demanding conditions.


Designed to make the job at hand so much easier, the Large Bore Metric fitting is the product of Philmac’s unrelenting commitment to continuous improvement and a culture based on innovation and ingenuity.


Fast and Easy Installation - 
Slide & Tighten™ technology:

Philmac Large Bore Metric incorporates all the benefits of Philmac’s Slide & Tighten™ technology. Simply insert the pipe until the first point of resistance is felt, and then tighten the nut up to the flange of the fitting body. No pipe preparation is needed and no force is required to push the pipe past the seal, so installation couldn’t be faster or easier. The advantage becomes even more significant in the larger sizes due to the cumbersome nature of large diameter pipes.
Easy Disassembly:
The fitting has been designed so that the once the nut is backed off 3 threads the pipe can easily be removed from the fitting.

Complete Security - Dynamic Sealing Method:
The mechanical advantage of the nut thread is used to push the seal into a compressed position, eliminating resistance when inserting the pipe into the fitting, so there is no risk of seal distortion or displacement.
Visual stop:
The flange on the body of the Philmac Large Bore Metric fitting provides a visual stop to indicate when the nut is fully tightened. This removes any uncertainty from the installation process.

No Loose Components:
Although disassembly of the fitting is not required for installation, if the nut is removed there is no danger of losing components as they are all retained within the nut. Losing components in the trench becomes a thing of the past.

Designed to minimize pipe twist:
The fitting has been designed to minimize pipe twist as the nut is tightened. Maximum pipe twist is approximately three quarters of a turn compared to one and a half turns with many other fittings. Pipe twist can impact not only on the connection you have just made but also on the connection at the other end of the line.
Philmac Large Bore Metric is WRAS (UK), WSAA and WaterMark approved (Australia).
High Performance Materials - Made from advanced thermoplastic materials:
Philmac Large Bore Metric is manufactured from lightweight high performance thermoplastic materials with outstanding impact, UV, chemical and corrosion resistance. The material is non-toxic and taint-free.
