Flash arrestors are typically used on torch applications but should also be used in systems where you want to protect your upstream equipment from the backward progression of a flame. The 6103A Series are dry type flashback protection devices, featuring high purity materials and design.  The Model 6103A Series is constructed of brass and neoprene with a stainless flame barrier, and is ideal for protecting fuel systems in laboratory applications.

Design Features

• Provides positive shut-off of gas and checks the reverse flow of gas under most conditions
• Extinguishes flame within the housing which prevents the flame front from reaching the gas supply.
• Reusable – can be reset and reused after a flashback occurs (maximum of three (3) times recommended)

Safety Elements

• Non-Return Valve (Check Valve): Prevents the gas flowing in the reverse direction to the normal flow.
• Inlet Filter: 100 micron stainless steel sintered filter.
• Flame Arrestor: Stainless steel flame barrier positively extinguishes flame within the housing.
• Thermal Cut-Off: Cuts off gas supply when the safety device is overheated (165 C) due to an external flame or a flame returning from downstream.

Materials of Construction

• Body: Brass
• Seat: Neoprene
• O-rings: Neoprene
• Internal Parts: Brass and Steel
• Leak Rate: Bubble Tight

Specifications
