As a non-torque sensitive graphite rupture disc, Universal Arma-Gard has a holderless design for easy installation between industry standard flanges (PN, ANSI, BS).

Arma-Gard is suitable for applications operating at low to very low pressures. The stainless-steel armoured ring protects the graphite disc both during installation and when in use. The bursting disc is therefore not affected by misaligned, poorly supported pipework or uneven torque tightening of pipe flange bolts.
