ISO 6195:2013 specifies dimensions and tolerances of housings for wiper rings used in reciprocating rod applications for fluid power cylinders. The range of rod diameters is from 4 mm to 360 mm.

ISO 6195:2013 is applicable to the following five housing designs.

• Type A: recessed housings with undercut or separate cover to retain elastomeric wipers.
• Type B: open recessed housings for wipers with integral rigid enforcement, that are press-fit in the housing.
• Type C: recessed housings with undercut to retain elastomeric wipers (these are the preferred housings for double lip wipers without integral rigid enforcement).
• Type D: recessed housings with undercut to retain elastomer-energized, plastic-faced wipers.
• Type E: recessed housings with undercut or separate cover to retain elastomeric wipers (these are the preferred housings for single lip wipers without integral rigid enforcement).
