Schedule 80 Uniseal Tank Adapter
The Schedule 80 Uniseal adapter is preferred when a leak-resistant, removable feedthrough is required — its compressible rubber seal handles irregular cables and probes and provides pressure-rated, reusable sealing that rigid bulkheads cannot match. Although it can be pricier per pass-through than simple PVC bulkheads, its technical advantage for vibration resistance and tool-less removal makes it the go-to option for delicate sensors and retrofit installations where maintaining a tight seal is critical.
