The Best From The Best: Fike G2 Technology

Rupture discs are a symbol of trust. That’s why for 75 years we’ve worked every day to achieve the highest operating ratios, tightest burst tolerances and greatest life cycles.

This dedication has resulted in the development of Fike's patented G2 manufacturing technology, which produces the most trusted rupture discs ever assembled.

Protect Your Pressure Relief Valves

Fike's ValveGuard strategy uses rupture discs in tandem with pressure relief valves (PRV's) to prevent fugitive emmission, protect PRV's from blockage and viscous media and allows the use of standard PRV's in corrosive environments. All of these factors reduce the need for costly maintenance and extend the lifetime of the PRV.
