ABSTRACT:
A seal anchor for pipe couplings suited for frictional connection of smooth-ended pipes. The seal anchor has a housing, and at least one sealing element, for example of rubber-elastic material, arranged therein. The anchor may be of generally L-shaped cross-section and has a first limb extending in the axial direction and a second limb extending at an acute angle to the first limb. The anchoring element blank is provided with slots which run across its width in the longitudinal direction relative to the limbs and between the limbs. One or more webs span the slots to join adjacent limbs.
