Two seals for the CO2 pressure regulators by Hiwi we offer. Reliably seals off the connection between pressure regulator and CO2 cylinder and thus prevents unnecessary CO2 loss.
For safety's sake, check the dimensions on the connection piece of your pressure reducer in advance.
If you have a lsightly older Double Stage Pressure Regulator, you might need the hard, white seal.
Hiwi is a renowned German manufacturer of CO2 pressure regulators. The highest level of quality and a long useful life are in their focus. These high quality standards do not exclude attractive prices, though.
Especially in aquascaping, the addition of CO2 for the plants is something very basic, and thus it is really important to choose good CO2 supplying equipment. Hiwi meets even the highest quality standards in every aspect und is thus the best choice when it comes to CO2 pressure regulators.
