SI TECH Balder Quick-On Drysuit Inflation Hose
This heavy-duty rubber OEM hose from SI TECH has a standard UNF 3/8-inch male fitting that connects to the low-pressure port of the first stage and Balder quick-on female fitting that connects to the standard International (aka Schrader) nipple commonly seen on drysuits in recreational diving. The quick-on design makes it simple – no need to pull the locking collar back to connect just press it on. The Balder Quick-On design also has fewer O-rings and components, making maintenance easier. Available in { 32 in | 80 cm } and { 36 in | 90 cm } lengths.

Customer Reviews

There is NO universal standard that defines the precise shape and exact dimensions of the compressed gas quick-connect coupling systems used on BCD and drysuit inflators. The different low-flow posts are in theory compatible with the same Schrader valve female coupler, thus you will often see inflator hoses with the same BC QD coupler marketed for use with both BCD and drysuit inflation valves. However, in our experience the hoses with couplers designed for one style of post are less likely to be entirely compatible with another style post. We have also encountered occasional incompatibilities in the fittings even within the same style, especially when there are many years difference in age between the female coupling and the male post.
These circumstances can cause compatibility issues with the connection: the fittings will not connect at all; the fittings will not securely connect and can self-disconnect without any overt user action; the fittings will securely connect but gas will not flow; the fittings will connect but can exhibit leaks. Whenever using 3rd party connectors you should always be careful to validate compatibility of the connectors.
