Description

Two seals for the CO₂-pressure reducers from Hiwi. They secure the connections between pressure reducer and CO₂-cansiter which helps prevent unnessesary CO₂-loss.

Please Control the dimensions of your pressure reducer before purchase to make sure you receive the correct size.

For the older pressure reducers, resp. the CO₂-nozzle with a slightly tilted case, the redish, soft seal is recommended. The white, hard seal fits the newer CO₂-pressure reducers without a tilted border.

Hiwi

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.
