Water blocks bridge EK Water Blocks

EK-Scalar Terminal Dual 4-slot is a parallel interconnection designed to join two identical EK-Vector or EK-FC water blocks into a single, rigid unit. Manufactured from black POM (acetal), the terminal mounts directly to compatible water blocks and eliminates the need for additional linking parts. The product is intended for use on motherboards whose PCIe x16 slots are spaced 81.3 mm (3.2") apart and includes the mounting hardware and plugs for installation.

Advantages

The EK-Scalar Dual 4-slot terminal provides a clean, compact method to connect two same-type EK water blocks while maintaining solid mechanical stability. Made from durable acetal (POM), it offers precise fitment and a uniform black finish that integrates with most liquid-cooling setups. The package includes two G1/4 plugs and a mounting mechanism, simplifying installation while the installation manual explains the intended water flow.

Suitable for

• Connecting two EK-Vector water blocks in parallel
• Connecting two EK-FC water blocks in parallel
• Multi-GPU custom liquid cooling loops with 81.3 mm PCIe x16 slot spacing
• PC builds requiring a rigid, single-unit bridge between two identical GPU blocks

Key specifications

• Material: Acetal (POM)
• Compatibility: EK-Vector and EK-FC water blocks of the same model
• PCIe slot spacing requirement: 81.3 mm (3.2") between PCIe x16 slots
• Included items: 1x EK-Scalar Dual 4-slot (Acetal), 2x G1/4 plugs, 1x mounting mechanism

How to use

Align the EK-Scalar terminal with the two identical EK-Vector or EK-FC water blocks mounted on cards whose PCIe x16 slots are 81.3 mm apart. Secure the terminal to the water blocks using the supplied mounting mechanism according to the installation manual. Install the included G1/4 plugs where necessary, and verify flow direction as described in the manual before integrating the assembly into the loop and filling the cooling system.

Recommendations

Use the bridge only with two identical EK-Vector or EK-FC water blocks and confirm your motherboard's PCIe x16 slot spacing is 81.3 mm. Follow the manufacturer’s installation manual for correct flow orientation and secure mounting. Inspect fittings and seals after filling the loop and run an initial leak test before normal operation.
