Nautilus

Nautilus is the technical diving hardware and consumables range we keep for the small parts that hold a rig together: snaps and double enders, bungee and caveline, compasses and pressure gauges, hoses and adapters, cylinder bands and boots, oxygen greases and gas labelling. It is not a headline range. It is the drawer you go to when something needs replacing before the next dive.

About the Nautilus range

Nautilus is a technical diving hardware range rather than a headline equipment brand, and the contents of this collection reflect that: rigging hardware, line and bungee, hoses, adapters, gauges, cylinder fittings and consumables. A few items listed under Nautilus are supplied under their own names, among them the Christolube oxygen greases and the San O Sub oxygen rescue kit.

We have kept this description deliberately factual. Rather than tell a brand story we cannot stand behind, the section below sets out what is actually live in this collection today.

What we stock from Nautilus

Rigging hardware covers stainless double enders in 90 and 120 mm, a 120 mm stage bolt snap, a 30 mm split ring, a 26 mm shackle and a 27 mm bow shackle, 8 mm domed backplate nuts, a technical diving coach bolt and a stainless D-ring holder for hose clamps.

For line and bungee we stock bungee cord in 3, 4, 5 and 6 mm and by the metre, a stage cylinder bungee, braided polyester caveline in 1.5 and 2 mm on 200 and 500 metre spools, and an aluminium spool.

Instruments and hoses take in 52 and 63 mm submersible pressure gauges, including a 360 bar oxygen gauge and snap-fitted versions, a button gauge, a 300 bar cylinder pressure check gauge, and bungee-mount compasses at 22 and 30 degrees. Hoses run to medium pressure in 3/8 inch and half inch, a high pressure hose and inflator hoses, with an HP swivel pin and a regulator adjuster alongside them.

On the cylinder side we list stainless jubilee bands and a protective cover, single and twinset tank boots, a stage rigging kit and a cylinder valve handwheel. Adapters and fittings cover G5/8 and M26 threads in several combinations, including a T-adapter and a bullnose male to DIN 300 female fitting.

Consumables and sundries round it out: Christolube MCG111 oxygen grease in jar, tube and syringe, a San O Sub oxygen rescue kit, MOD depth decals in six depths, oxygen, diluent and argon cylinder stickers, coil lanyards in three configurations, heavy duty wetnotes, a foam-lined case, a toolmaster, and drysuit inflation systems and bottles.

Ordering the right part

Most of this range is defined by a thread, a diameter or a pressure rating, and those have to match the equipment you already own. Adapter and fitting threads in particular are easy to get wrong from a listing photograph. Check the manufacturer specification for the kit you are fitting the part to, and if you are unsure, bring the old part into the shop or get in touch and describe it. For rigging hardware it is also worth seeing the wider clips, snaps and D-rings range to compare sizes and gate types.

Who it suits

Technical and twinset divers, and anyone maintaining or reconfiguring their own kit. Much of what is here is replacement and rigging hardware rather than a first purchase, which is why it is worth knowing the range exists before you need it.

Frequently asked questions

Technical diving hardware, spares and consumables rather than headline equipment. Currently that covers rigging hardware including double enders, a stage bolt snap, split rings, shackles, domed backplate nuts and a stainless D-ring holder for hose clamps; bungee cord in several diameters and by the metre, plus braided caveline on 200 and 500 metre spools and an aluminium spool; 52 and 63 mm pressure gauges including an oxygen version, a button gauge and a cylinder pressure check gauge; bungee-mount compasses; medium and high pressure hoses and inflator hoses; G5/8 and M26 adapters and fittings; stainless jubilee bands, tank boots and a stage rigging kit; drysuit inflation systems; Christolube oxygen greases and a San O Sub oxygen rescue kit; MOD decals and gas stickers; and sundries such as coil lanyards, heavy duty wetnotes, a foam-lined case and a toolmaster.

Check the thread and pressure rating of the equipment you are fitting it to, because that is what determines the answer and it is very easy to get wrong from a photograph. Adapters in this range run across several thread standards, and a fitting that looks right can be the wrong one. Check the manufacturer specification for your kit, and if you are unsure, bring the old part into the shop or get in touch and describe it to us.

Yes, and with rigging hardware in particular we would encourage it. Snaps, double enders and shackles are far easier to judge in the hand than on a screen, because gate action, size and how a snap sits against the rest of your kit all matter. Come into the shop and have a look, and bring the equipment you are fitting it to if you can.

Ask us. This range runs to a lot of small parts and what we list is what we currently hold. If you cannot find the equipment you are looking for, please get in touch and describe what you need and we will let you know whether we can source it.
