Santi Drysuit Connector – Power for Heated Gear
The Santi Drysuit Connector links your Santi heated vest, gloves, or undersuit to an external battery via your existing drysuit inflation valve.
You simply install the connector underneath your current drysuit inflation valve to maintain full inflation functionality while adding thermal power.
Installation and Valve Compatibility
To set up the system, you screw your existing drysuit inflation valve directly onto the top of the connector unit. Because diameters differ between brands, you must select either the Apeks or Si-Tech version to match your current gear. The connector adds 19mm in height to your standard valve assembly once fully installed.

Furthermore, the internal cables measure approximately 55cm to reach your Santi heating systems, including heated undersuits, vests, and gloves. This design ensures a secure, waterproof fit for your technical diving needs.
Comparing Drysuit Connector and Thermovalve
While the Santi Drysuit Connector uses your existing hardware, the Santi Thermovalve 303 offers an all-in-one alternative for more streamlined diving. In contrast, the Thermovalve integrates the inflation and power functions into a single, low-profile unit.

Transitioning to this connector allows you to upgrade your drysuit heating system without replacing your trusted inflation components. It remains a cost-effective solution.
Santi Drysuit Connector Product Highlights
- Seamless power integration passes electricity through your existing valve port to power heated gear.
- Compatible with Apeks and Si-Tech systems, ensuring a perfect fit for most drysuit brands.
- Maintains inflation functionality by allowing your original valve to screw directly onto the connector.
- 55cm internal cabling provides ample length to connect to heated vests or undersuits.
