Agilent, CP738499, Ferrule, LOWOX Vespel, 1/32 in. od x 0.75 mm id, 1/pk

CP738499 is an Agilent LOWOX Vespel ferrule identified for a specific gas chromatography connection size. The manufacturer's part description lists a 1/32 inch outside dimension, a 0.75 mm inside dimension and one piece per package. This is a low-oxygen, Vespel-based consumable fitting rather than a complete union or column. Ferrules help create mechanical seals around appropriately matched GC tubing and are routinely considered when servicing chromatographic gas pathways. Careful fitting selection can reduce unwanted air ingress and gas leaks that lead to instability or reduced separation performance. Because very small dimensional differences can affect fit, match this ferrule against the original installation drawing and mating hardware. Do not replace it with a general-purpose 1/8 inch ferrule, which represents a different connection size.
