The Oldham Seals range of “Jetpac®” Rubber Flexible Hoses and Expansion Bellows have been Type Approved not only to our United Kingdom’s Ministry of Defence Naval Standards, but also to other Type Approval Classifications such as:

Lloyds Type Approval

Det Norske Veritas

American Bureau of Shipping

UK MOD Def Stan 02-345

Germanischer Lloyds

The fact that our Integral Fire Retardant Hoses and Expansion Bellows have been Type Approved to these classifications has proved to the Marine Industry the benefit of using Oldham Seals Jetpac® range of hoses and expansion bellows in conjunction with reliability.  The other benefits are:

  • A major cost saving in expensive downtime through longer operating performance
  • Design advantages by using the wide range of Jetpac® configurations
  • Greater reduction in vibration levels
  • Greater reduction in noise levels
  • Substantial weight saving over traditional metallic pipework arrangements

In many recent cases, metallic pipework has been replaced through corrosion and cracking, and replaced with Jetpac® hoses.

Oldham Seals Ltd have managed to design one material construction formula to withstand most ranges of fluids used within a naval ship or submarine, thus ensuring a cost effective product.

Oldham Seals Ltd manufacture a range of integral fire resistant hose and bellows, which eliminates the need to fit fire guards (which have to be removed at regular intervals to check the hoses or bellows), thus resulting in less maintenance involved. There is no requirement for Jetpac Bellows to use restraining rings, which also results in weight saving and a cost saving.
