Frequently Asked Questions

AI
You must check your equipment's technical manual or measure the inner and outer diameter of your existing pipe. Even a few millimeters of difference can result in a poor seal or total incompatibility.
Many aftermarket options offer similar or even better durability at a lower cost, but you should verify the material (such as aluminum or PVC) and the seal type to ensure they meet your specific pressure requirements.
