Ansul 42in Actuation Hose - 430815

The Ansul 430815 is a 42-inch high-pressure actuation hose used to connect actuation components in ANSUL suppression systems. Built to withstand the system's discharge pressures, this hose bridges the gap between actuation hardware — such as the Automan control head and connected cylinders or manifolds — where the installation distance requires an intermediate-length hose that is longer than short jumper hoses but shorter than extended-length assemblies. The 42-inch length covers a specific range of installation configurations in ANSUL R-102 and compatible system layouts.

Selecting the correct actuation hose length is critical for ANSUL system reliability. A hose that is too short creates installation tension that stresses the end fittings and can cause premature fitting failure. A hose that is excessively long creates loops or sags that accumulate grease in kitchen environments and can create friction resistance that delays or reduces the actuation pressure signal. The 430815 at 42 inches provides the correct spanning distance for the specific installation configurations it is designed for in the ANSUL R-102 system documentation.

Built for durability in high-heat commercial kitchen environments, the 430815 high pressure hose for nitrogen actuation service is available through authorized ansul distributors. Inspect at every semi-annual NFPA 17A and NFPA 96 service visit for cracking, kinking, fitting corrosion, and grease accumulation. Replace if any defect is found — a compromised actuation hose can prevent the full actuation pressure signal from reaching the agent cylinder valve during a real fire event. Document hose condition in the fire suppression system inspection record.

Inspect the 430815 at every semi-annual NFPA 17A and NFPA 96 inspection. Check the full 42-inch length for cracking, kinking, abrasion, and grease contamination. Inspect both end fittings for corrosion and thread damage. A high-pressure hose with any crack or structural compromise must be replaced immediately — a hose failure during actuation can prevent the suppression agent from reaching the cooking equipment hazard zone. Replace with a new 430815 OEM hose sourced through authorized ansul distributors. Document condition in the fire suppression system inspection record.

What is the difference between the 430815 and the 032336 braided hose?

The 430815 is a 42-inch high-pressure actuation hose for ANSUL suppression system actuation connections. The 032336 is a 24-inch braided hose also used in ANSUL systems. The two differ in length, construction type (actuation hose vs braided hose), and intended application within the system. Select the correct hose based on the specific connection being serviced per the ANSUL R-102 system documentation — never substitute one hose type or length for another.

Can I use a generic high-pressure hose as a replacement?

No. The 430815 is rated and listed for ANSUL system operating pressures and is manufactured to the correct end-fitting specification for ANSUL system connections. Generic high-pressure hoses may not meet the pressure rating, chemical compatibility, or fitting geometry required. Using non-OEM hoses voids the ANSUL system's UL listing.
