The Viking Neck Ring System comprises 5 separate components as follows:

• Outer rubber neckring mounted on black rubber
• Inner rigid plastic lock ring
• Latex neck seal
• Optional hood made from latex, rubber or neoprene
• Outer "O" ring lock rings (2)

The outer rubber ring mounted on black rubber material is mounted to the suit by vulcanisation and taping. The latex neck seal is then mounted inside the outer rubber ring using the rigid plastic lock ring with the latex seal folded around the lock ring.

The hood is fitted over the outside of the rubber ring and held in place by the 2 "O" rings.

If the hood or latex neck seal breaks, then removal is the opposite of fitting, and then follow above instructions to fit the replacement parts.
