O-ring, Buna FDA

Part number 629932 is a Buna-N (nitrile) O-ring designated for use with Marlen vacuum stuffing equipment. It is sized for a specific sealing interface within the machine and is not interchangeable with part number 1136-353, which serves a separate sealing location.

The O-ring forms a leak-tight, compressible seal at its designated interface within the Marlen stuffer. Buna-N construction provides reliable resistance to oils, fats, and meat emulsions typical of sausage stuffing operations, making it well suited for the process conditions encountered in this application.

The material carries an FDA rating confirming suitability for food-contact environments. Marlen vacuum stuffers incorporate multiple O-ring-sealed interfaces — including piston cylinders, valve seats, hopper covers, pipe fittings, and stuffing horn connections — and correct size selection is required to maintain seal integrity at each location.
