Oldham Seals designs, manufactures, tests and manages Jetpac® flexible pipe systems for the fuel, cooling, ballast, bilge, fire-main and propulsion systems that have to keep working under shock, vibration and fire. Designed to your pipework. Type approved. Supported on board for the life of the vessel.

designed and manufactured in Chichester, England [✓ L10: Lee, "pretty sure it's '64"]
Start with the problem in front of you. Each card points to the Jetpac® products, or the Jetrac service, that answer it.
A high-shock, high-vibration construction that absorbs movement instead of transmitting it, and cuts structure-borne noise. [⚑ L4: second Def Stan heard as "4732" on the call; confirm the number]
Shaped to your pipework layout, not the other way round.
The fire resistance is in the rubber itself, so there are no fire sleeves to fit or inspect. Def Stan 02-345: 15 minutes at 1,100°C while pressurised and vibrated. [✓ L4: always "fire-resistant"]
Replace the rigid metallic run with a flexible one: no restraining rings, less weight, one material family across sea water, fuels and oils. [⚑ G6: fluid list current]
Each hose has a recommended replacement date, and its replacement should be ordered before that date arrives.
The full Jetpac® range, bespoke assemblies and fittings included. Send us the drawing.
→The five cards and their order follow the home page layout note "Customer problem – Products on Home Page". Difficult installation challenges, the sixth Solutions page, is not one of the five; it stays in the Solutions menu and on the Solutions hub. The lines in italics are drafts written for the wireframe: the sales team's own buyer questions replace them. [⚑ L5: Georgia → Connor, Mandy, Jill and Becky]
No bore or pressure figures on the cards. [✓ L3: no spec table. The range runs from very small to very large and from very low pressure to very high, and a token table undersells it] By-pass valves stay off the homepage. [✓ L3: optional; Lee is 50/50 and it is the first to go if space is short] Suction entry feet are now named, on the Corrosion & Pipe Failure card. [✓ 8 Oct] Ducting sits under Vibration and Movement, not Fire. [✓ 8 Oct]
IMAGE BRIEF — one photograph per card from the May 2026 shoot, consistent angle and ground. In design the cards take the Rubbercraft (RCC) homepage treatment: a full-bleed photograph with the problem title over it and the products revealed on hover, closing on the "View all products" tile.

Hotspots follow Georgia and Lee's 8 Oct mark-up: davits and replenishment at sea (RAS) added on the surface ship; weapon handling systems and weapons and sensors cooling added on the submarine, with air and fume ducting moved down into the hull. [✓ 8 Oct] If more applications are to be featured (the brief was 12 to 15), Lee labels each one submarine only, surface ship only, or both. [⚑ L5: Lee] The 3D walk-through stays a separate add-on.
It sits exactly where the movement, the heat and the shock are. That is why it is flexible, and why the choice matters more than its size suggests.
Machinery and pipework move and expand. The flexible assembly takes that movement so the rest of the system does not have to.
Shock and vibration reach the flexible assembly first. It absorbs them, which stops them passing through to the rest of the system.
In a fire environment the assembly still has to maintain pressure. Jetpac® does this with its integrated fire protection, eliminating the need for fire sleeves.
Corrodes, cracks and carries every vibration into the system.
Limited movement across multiple planes, so less suited where movement comes from several directions at once. A rubber hose is a true multi-axis connection. [⚑ Q3: OK to lead with this rather than the suggested fire-guard line?]
No naval type approval. And in a fire environment, Oldham Seals hoses are low toxicity compared with some industrial hoses. [⚑ Q4: test data behind low toxicity? "No naval type approval" kept]
Movement in all three planes. Fire-resistant in the rubber itself, so no fire sleeves. Type approved before it goes on board.
[⚑ L9c: section copy comes from Lee's "Flexibility Matters" slide, revamped as a mini white paper and the first capability story with no vessel named. Lee to send it to Carlos] The three points above are wireframe drafts until it arrives.

Jetpac® is the product: fire-resistant flexible pipe systems, designed and manufactured in Chichester. Jetrac is the service: the Oldham Seals field division that surveys, registers, replaces and installs flexible hoses on board. Most suppliers stop at delivery. That is where Jetrac starts.
Straight and preformed hose assemblies and bellows in one integrally fire-resistant material, built to your pipework and qualified before they go on board. [⚑ Q2: ducting is off this card and the Fire card. We read "not integrally fire resistant" as the ducting, not the hoses. Right?]
See the Jetpac® range →Engineers on board to survey flexible hoses, tag them, record their condition and criticality in a web-accessible register, forecast replacement and install. Other manufacturers' hoses included.
Jetrac Hose Integrity Management →A hose is recommended for replacement on a 5-, 10- or 15-year periodicity [✓ L9a]. This is what happens between fitting it and replacing it.
Jetrac engineers go on board and survey the flexible hoses and bellows, whoever made them.
Each hose surveyed gets a tag and an entry in the Jetrac register: location, specification, condition, criticality.
Application good, hose good. Or: this one is starting to crack and needs exchanging. A report, not a guess.
Replacement dates planned against upkeep and refit periods, so nothing expires before its replacement is ordered.
Oldham Seals manufactures and supplies the replacement.

Three businesses, one fluid system. Oldham Seals designs and manufactures it. Jetrac surveys, registers and installs it.

Oldham Seals supplies the UK MOD and its prime contractors, and exports to navies around the world. The map names countries only: never a class, a programme or what was supplied.
Almost everything Oldham Seals manufactures goes to sea with naval surface ships and submarines, for the UK MOD, its prime contractors and export navies. The commercial marine, offshore and specialty work we take on gets the naval qualification path, not a lighter one.

Fire-resistant. The resistance is in the rubber itself, so there are no fire sleeves to fit. The standard is Def Stan 02-345: 15 minutes at 1,100°C while pressurised and vibrated. [✓ L4]

Hoses are recommended for replacement on a 5-, 10- or 15-year periodicity, depending on the application. Jetrac tracks the dates of the hoses it surveys, so the replacement is ordered before the hose is due. [✓ L9a]
