"Custom Built Regulator Servicing Tools"

We manufacture high quality reasonably priced scuba regulator tools for export worldwide. If the item you are looking for isn't listed here we can probably make it for you. We can also machine custom dive parts on request, no matter how large or small your order, including for the technical diving market. We also differ by our highly competitive shipping charges.

We supply in line adjusters for virtually all available regulators, interstage pressure testers, combinations of the two, assembly and disassembly tools, bespoke stainless steel items and much more, all made to a high standard. We will also quote for repairs for that irreplaceable item that is now broken or worn.

With over 40 years in the dive industry including currently running a highly successful dive centre and repair/servicing outlet we have the experience to know what your standards and expectations are for quality, price and service provision. We encourage you to shop around and then try us last for your requirements. We also offer a full after sales service on all our items.

Here are just a small selection to show the quality of the fabrication.

	Fed up with the standard VR3 or VR2 battery cap key? We were too so here is a robust replacement that fits the cap perfectly making removal and replacement a very simple task. The last thing you need it a delay in changing the battery leading to loss of data, this key prevents it happening.
	This is so clever and just off the design board. You may have seen the bulky metal swivel that many divers attach to the Oceanic Omega 2nd stage to make it a more comfortable dive. You may even have noticed that Oceanic have now designed an integrated hose and swivel that is a retro fit for their newer regs. GAS Tools have designed an adapter that means that this excellent new swivel design can be fitted to ANY make of regulator. The photo left is it fitted to one of my Zetas but I have also tested it on Sherwoods and Apeks. You get the added comfort and flexibility without the increase in weight.
	In line adjusters, all makes, including Posidon, Mares, Scubapro, Oceanic etc. Either simple design (shown or with additional interstage pressure gauge added). These are top quality and small enough to carry in your spares kit as well as in the workshop.
	Hexdrive version
	Unique tool for adjusting the Oceanic swivel octopus, the only tool available to adjust flow rates while connected to an air source.
	Brand new for the recently released Delta second stage from Oceanic. This type of fit will also be a retro fit for all other Oceanic regs so this addition is a valuable tool for any Oceanic technician.
	Any stainless steel product fabricated. Here are some valve protectors made to a customers particular requirement. Just email your requirements for a quote
	We have introduced these new stainless backplate screws to do away with the traditional flatblade screw and come with a hex screw and torque bar that also fits cylinder DIN inserts.
	A clever tool for seperating the Oceanic 1st stage DIN adapter without recource to wrenches, vice etc.
	Another new addition, the Sherwood set. These cones are machined to fit the moving orifice, piston and maximus 2nd stage and permit simple fitting of the required o-rings. A HP seat removing tool is also included.
	Oceanic service tools made including the shown knife edge remover for the DX3/4. We also produce pin drifts for the Omega/Zeta, HP seat removers for the DX2 and much more.
	Brass or SS 1st stage holding bars, any length, HP or LP ports, both and Posidon threads made.
	LP hoses made to order, any length and in any of the depicted colours, ideal for stage cylinder differentiation, nitrox or simply to make your AAS stand out.
	Take your pick from these colours!
	Simple and effective; test the interstage pressure with ease by plugging into the LP hose, any makes catered for. We can also produce any type of gauge/configuration for your workshop.
	Custom made stainless steel O ring tools, a handy addition to any divers kit.
	An interesting adaption of a cylinder tank valve. Great device for your tool kit and as part of your kit to ensure you get to the dive site with a full serving of gas.
