Spring Seals

Spring Seals (Spring Energised Seals)

Spring Seals from M Barnwell Services provide a spring energised sealing solution for static, rotary and reciprocating applications. With a wide temperature range, excellent performance at high and low pressures they are the answer to sealing problems where conventional products fail to give the integrity or reliability required.

Spring Seals are manufactured in various standard (BS1806 and BS4518) or non-standard sizes allowing them to be retrofitted into existing O-ring grooves.

Spring Seal

Also known as S-seals and all-in-one T-seals, Spring Seals contain a high modulus elastomer and two integrated anti-extrusion springs. They are used to effectively seal applications that are subject to:

  • Chemical attack by oilfield media
  • Large clearance gaps
  • High pressure (bi-directional)
  • Remote hardware makeup
  • Restricted access for seal installation

Steel Springs provide excellent strength, however, PEEK springs are ideal for low wear applications where metal-to-metal contact with the housing is a concern.
