312WHSF - CK Worldwide 40V74SF Replacement Super-Flex Water Hose

Premium Cooling for High-Performance TIG Welding

The CK Worldwide 312WHSF is a high-quality replacement water hose designed to maintain the thermal efficiency of your water-cooled TIG torch system. Engineered for professional welders who demand reliability, this hose is an essential component for 3 Series TIG torches. It serves as a direct replacement for the industry-standard part number 40V74SF, ensuring seamless integration with existing equipment without the need for adapters or modifications. Proper coolant flow is critical for preventing torch overheating, protecting internal power cables, and extending the lifespan of your consumables; this hose delivers that performance with the added benefit of CK Worldwide's superior construction quality.

What sets the 312WHSF apart is its "Super-Flex" design. Unlike traditional vinyl or rubber hoses that can become stiff and cumbersome, particularly in colder environments, Super-Flex hoses are constructed from high-grade silicone tubing encased in a durable nylon overbraid. This combination provides exceptional flexibility and kink resistance, allowing the coolant to flow freely even when the torch is manipulated into difficult positions. The 12.5-foot length is the standard configuration for most bench and booth setups, offering ample reach while minimizing the pressure drop associated with longer cable runs.

Compatibility is a key strength of this product. It is engineered to fit a broad range of CK Worldwide torches, including the CK300, CK350, CK510, CKA35, and CKM350. Furthermore, it adheres to standard industry fittings, making it compatible with 3 Series torches from other major manufacturers such as Weldcraft, Lincoln Electric, WeldTec, and Profax. Specifically, it fits torch models including the 17, 18, 26, 150, 210, 300, 510, Trimline, FL3L, and various CKM series bodies. Whether you are maintaining a single station or stocking parts for a diverse fleet of welding machines, the CK 312WHSF offers the versatility and durability required for industrial fabrication environments.
