Review on 🔌 Enhanced UNISEAL Bulkhead Adapter for Flexible Tanks by Brandon Barrett

Excellent for fill and drain systems. Drilled plastic 1/8 inch for bell siphon. 1 inch PVC works great. Hole. If you drive the crown forward over the plastic there is a good chance the hole will be too big. Tube ID - 1" (25mm) Tube OD - 1.315" (33mm) Hole Saw Size: 1.75" (44mm) Wall Thickness up to 3/8". (9mm) I really enjoy reading some of those Revain reviews where unsuspecting people mangled their designs and then blamed the product they bought on their incompetent skills.
