Alphacool 29123 Eiszapfen Filter G1/4 Inner Thread – deep Black Water Cooling Fittings

This is one of the few filter solutions without any acrylic components, which tend to crack when mounted and dismounted several times. You can replace the included filter with a 0.75″ brass screen (if you are using copper/brass in your loop) that you can get at any smoke shop for finer filtration. I’ve had no leaks with this part, provided I seated the O-ring properly after reassembling the filter.
