This set of connectors is listed as and intended for a more permanent, plumbed in installation, with right angled connections which are vulnerable to damage if used on a filter that is moved about.
The fittings are high quality but simply not suited to the way you planned to use the filter. If you havent sourced a replacement set please contact us as we will gladly send you the more suitable in-line ones which I have used personally for 3 years without incident.
