The insert holder consists of an inlet and outlet piece with seating surfaces machined to form a gasket seal with 30˚ seat rupture discs.
The insert holder fits ASME, DIN, or JIS companion pipe flanges and includes pre-assembly screws and side clips for bench assembly.
LaMOT rupture discs and holders both include permanent flow direction tags for easy visual verification of correct installation. Wherever specific holder identification tagging is required, the nameplate on the full bolted holder will also include a stainless steel customer identification tag.
