Back Up Rings

Kefloy Spiral BakRing® Type S

Spiral BakRing® is used to prevent extrusion of rubber O-Rings and rubber X-Rings. It consists as standard of two windings which in the ends are cut in an angle. It can be used for static as well as for dynamic applications. It should not be used for rotating applications. As it is “open” it can be installed at places where solid Back-up Rings are impossible to install. It adapts easily to big temperature changes.

Kefloy Uncut BakRing® Type U

Uncut BakRing® is used to prevent extrusion of rubber O-Rings and rubber X-Rings. It is a solid ring with a rectangular cross section. It can be used for static as well as for reciprocating and rotating applications.

Kefloy Heavy Duty BakRing® Type H

Heavy Duty BakRing® is used to prevent extrusion of rubber O-Rings and rubber X-Rings. It is a solid ring with a concave cross section. The concave contact surface against the O-Ring protects the O-Ring against deformation. It can be used for static as well as for reciprocating and rotating applications.

Spring Energised Piston Seals

MupuSeal® R Type 3062

Is a single acting spring energized piston seal for static and semi dynamic applications. MupuSeal® R consists of jacket of Kefloy® energized by a spiral spring. The steel spring is available in three different chemical resistant alloys.

  • Stainless steel AISI 301; DIN 1.4310
  • Hasteloy™ C-276; EN ISO 15156; NACE MR-01-75
  • Elgiloy™ ASTM F1058; EN ISO 15156; NACE MR-01-75

Hasteloy™ is a trademark of Haynes International Inc. Elgiloy™ is a registered trademark of Elgiloy Specialty Metals MupuSeal® R has symmetric sealing lips. The helical wound spring gives a high spring force which ensures excellent sealing capacity. MupuSeal® R is excellent for static applications and applications with a very little movement. MupuSeal® can be used with virtually all fluids. MupuSeal® is pressure responsive.
