The Straight Strain Relief fittings feature a molded O-Ring groove. The Snap Elbows and some of the Conduit Fittings do not have recess for an O-Ring. In that case, the Seal Ring would be the best choice, unless the hole can be beveled to accommodate an O-Ring. If NEMA 4x or 6 (European IP 68 - submersible) is required, O-Rings or Seal Rings should be used when mounting Strain Relief Fittings to a control panel, secured with a locking nut.
