O-rings and X-rings
Used in many applications, o-rings are the low-cost simple sealing solution. Available in a variety of compounds, hardnesses, colors, and industry related certified materials. Also available as extruded cord.
X-rings, also known as Quad-Rings®, are used for static and dynamic sealing. With multiple points of contact, x-rings have double the sealing function of o-rings and require less pressure for a tight seal.
