NPT Sealing Rings & O-Rings

Major Electronix handles the complete line of Sealcon Seal & O-Rings for NPT thread. They range from 1/4" to 1-1/2" and are made from Buna-N, silicone, or Viton material. Buna-N, also known as nitrile rubber, O-Rings are the most often used. They are black and have an operating temperature of -22 F to 248 F (-30 C to 120 C). Silicone O-Rings are orange with an operating temperature of -76 F to 482 F (-60 C to 250 C). Viton O-Rings are teal, with an operating temperature of -40 F to 392 F (-40 C to 200 C). Seal rings are polyethylene or fiber reinforced plastic. Seal rings are used when the cable gland does not have a bevel for an O-Ring.
