Green Goods Bulkhead Fittings U300 Editorial Review
The 3 UNISEAL Flexible Tank Adapter Bulkhead is a product that can be used in various situations such as connecting an inground rubber pond liner to a 275 gal tote and connecting a 3inch RV waste tank drain valve to 3inch pvc pipe. However, some customers found it a little tough to install and recommended using a bulkhead adapter for long-term durability. The product has a 3" uniseal with an outside diameter of 5". Some customers were pleased with the service and delivery of the product and found it worked well. However, some customers found that it did not fit well even on straight buckets and that the instructions were not accurate. A few customers had issues with the product and stated that it would be a great product if it were engineered slightly better.
