14778-4-10 - Smith Quickbraze 10ft Kevlar Twin Hose Replacement Kit

Advanced Kevlar Construction for Precision Brazing

The Smith Equipment 14778-4-10 Quickbraze Kevlar Replacement Brazing Hose represents a significant leap in material science for oxy-fuel applications. Unlike traditional rubber hoses that can be heavy, stiff, and prone to rapid degradation in high-heat environments, this hose utilizes a specialized Kevlar composition. Kevlar, a para-aramid synthetic fiber, provides exceptional tensile strength-to-weight ratios, making this hose incredibly durable while remaining surprisingly lightweight. For industrial applications where the operator is performing repetitious brazing motions—such as on HVAC assembly lines or automotive heat exchanger production—the reduction in hose weight translates directly to reduced musculoskeletal stress and improved precision over long shifts.

This 10-foot assembly is engineered specifically for the Smith Quickbraze ecosystem, ensuring seamless integration with the 11-1114 and 11-1116 torch handles. The regulator end is pre-terminated with standard Size B (9/16" - 18) fittings, ensuring compatibility with most industrial oxygen and fuel gas regulators. The torch end is designed for field termination or replacement; the kit includes the specific ferrules and a crimping tool required to securely attach the hose to the Quickbraze handle. This design choice allows for a secure, leak-proof connection that maintains the integrity of the gas flow, crucial for maintaining consistent flame characteristics during sensitive brazing operations.

Thermal resistance is another key specification of this product. In brazing environments, hoses are frequently exposed to hot metal, sparks, and radiant heat. The Kevlar outer jacket offers superior resistance to these hazards compared to standard rubber, prolonging the service life of the consumable and reducing the frequency of replacement. This hose is rated for Oxy-Fuel service, making it versatile for various fuel gases used in conjunction with oxygen. By investing in genuine Smith replacement parts, facilities ensure that their Quickbraze systems operate within safety parameters, maintaining the high flow rates and pressure stability required for quality brazing.
