Torque wrench end fitting EK Water Blocks EK-Quantum Torque STC-10/16, 1/4 inch hex, black

EK Water Blocks EK-Quantum Torque STC-10/16 torque wrench end fitting is a compact accessory for controlled tightening in water-cooling assemblies. Finished in black and manufactured in Slovenia, this end fitting accepts a 1/4" imperial hex key and is designed to work with the STC-10/16 Torque system. It provides a durable interface for applying precise torque to soft-tube compression fittings used in flexible tubing connections.

Advantages

The fitting offers a minimalistic, non-intrusive design without visible branding and is made to deliver consistent torque application when used with the matching torque system. Its black finish and compact form factor make it suitable for discreet installation. The component is compatible with a range of flexible tubing types and is intended to mate with EK-Quantum STC-10/16 compression fittings for reliable sealing and mechanical retention.

Suitable for

• Tightening STC-10/16 soft-tube compression fittings in PC water-cooling loops
• Applying controlled torque to fittings on PVC, EPDM, Norprene or silicone flexible tubing
• Maintenance and assembly tasks where a 1/4" hex torque interface is required

Key specifications

• Interface type: 1/4" imperial hex
• Color / finish: black
• Compatibility: designed for STC-10/16 torque system and corresponding soft-tube compression fittings
• Intended tubing types: compatible with flexible tubing such as PVC, EPDM, Norprene and silicone
• Origin: manufactured in Slovenia

How to use

Place the end fitting onto the torque wrench designed for the STC-10/16 Torque system and insert a 1/4" hex key as required by the torque tool. Fit the compression ring onto the soft tubing and slide the tubing onto the barb of the STC-10/16 compression fitting. Use the torque wrench with this end fitting to apply the specified torque until the wrench indicates the set value, ensuring consistent compression of the locking ring to prevent the tube from slipping off the barb.

Recommendations

Use this end fitting only with the EK-Quantum Torque STC-10/16 system and compatible compression fittings. Verify manufacturer torque settings for your specific fittings and tubing material before use. Avoid excessive force beyond recommended torque values to prevent damage to fittings or tubing.
