Alpha Resources O-Ring
Alpha Resources O-Ring is an aftermarket replacement O-ring seal for LECO elemental and combustion analyzers. It cross-references LECO part 771-991 and provides a gas-tight, leak-free seal in the analyzer's gas, combustion, or vacuum path — preventing the leaks that cause baseline drift, poor recoveries, and downtime.
Replace worn or hardened O-rings during routine maintenance to keep results accurate. Supplied by Alpha Resources as an aftermarket laboratory consumable.
