What is the best way to determine equipment size and fit?
XS Scuba provides wetsuit, BC and fin size charts on this website to assist with the proper fit. However, due to body shape variations, it is recommended that the item be tried on at your local XS Scuba Dealer before making your final purchase.
How do I get technical assistance on a product?
“When seeking technical assistance we always recommend speaking with the XS Scuba dealer whom you purchased the product from, or feel free to send us an email at firstname.lastname@example.org and we will be glad to help you with any assistance that is necessary.”
XS Scuba Product FAQs
Are XS Scuba Regulators compatible with nitrox?
My regulator was breathing fine at the surface but got hard to breathe or stopped working at depth. Why?
This is caused from a restriction in the air passageway. Air at or near the surface is less dense than the air we breathe at depth. The less dense air flows past the restriction while the dense air at depth is unable to. The restriction is most likely caused by one of these two things:
- The cylinder valve is not opened all of the way.
- The regulator filter is partially clogged. This happens because of corrosion and particulate matter located in the cylinder. If the filter is partially clogged you must take the regulator and the cylinder in for service. If you were not using your personal cylinder it is very important that you notify the owner of the cylinder to have it internally inspected and to make sure that the valve has a dip tube in place.
Miflex Braided Hoses
I read a DAN article recently about braided hoses degrading, causing internal crystals to block the air passageway. Are Miflex hoses, that XS Scuba distributes, subject to this degradation?
Answer from Miflex:
We confirm that Miflex has been actively involved with DAN to discuss and offer advice on the inspection process for diving hoses, in a very positive manner.
Please note that all Miflex hoses carry the full company marking and required data on the fittings, as required by EN250. Additionally in the packaging of every Miflex hose (LP & HP) we supply Miflex user information for use, inspection & warranty details. This is unlike the majority of manufacturers of diving hoses.
No hoses with laser markings showed disintegration problems.
DAN requested Miflex’s advice on the lifespan for diving hoses, and although Miflex advised that their hoses typically have a higher lifespan than other styles of hoses, they would recommend that hoses are actively reviewed for replacement every 5 years (typically circa 500 dives). This is also the standard adopted by most major diving equipment manufacturers as a time for sensible review & potential replacement.
Miflex is pleased that DAN has provided a positive report to assist divers with advice on how to inspect their hoses and look for signs of age and damage, as is prudent to do for all diving equipment prior to use.
Knives and FogCutters
Rust and Corrosion on Knife Blades
My knife / FogCutter blade is made of stainless steel. Why is there rust or corrosion on the blade?
The irony is that the higher the quality of stainless, the more it is likely to corrode. It all has to do with the carbon content in the steel.

How exactly do the filters work?
Which type of cylinder should I get, aluminum or steel?
As with many choices in life, there are pros and cons to each. We list some of the more common ones here and then you’ll need to consult with your local store or your instructor to determine which is best for you.
Twin Cylinder Bands
While installing my new tank bands, the nut seized on to the bolt. Why did this happen? How can I prevent it?
This is actually two questions but we’re feeling generous today!
Thread galling is a common, yet seldom understood problem with threaded fasteners. Galling, often referred to as a cold-welding process, can occur when the surfaces of male and female threads are placed under pressure. The frustrating aspect of fastener galling is that galled nuts and bolts may pass all required inspections (threads, material, mechanical, etc.), yet they still fail to function together.
Stainless steel fasteners are particularly susceptible to thread galling. During the tightening of the fastener, pressure builds between the contacting thread surfaces and breaks down the protective oxide coatings. With the absence of the oxide coating, the metal high points of the threads are exposed to one another, which increases friction. The combination of these two events can generate enough heat to fuse and seize the nut and bolt together.
Minor galling may cause only slight damage to the thread surface and the installer may still be able to remove the fastener. However, in severe cases galling can completely weld the nut and bolt together and prevent removal of the fastener. If the tightening process is continued once galling begins, the fastener may be twisted off or have its threads stripped.
Unfortunately, even with an understanding of the mechanism of galling, little is known on how to successfully control it. However, galling can be minimized with the following measures:
1. Clean the nuts and bolts
Scrub the threads with a toothbrush and detergent. Rinse thoroughly. Make sure that there is no visible debris.
2. Use the hex nuts rather than the nylon insert locknuts (Nylok nuts).
The most common stainless steel galling occurs with nylon insert lock nuts. We only include them in the kit to keep some of the old-timers from complaining.
3. Use a lubricant
The best lubricant for this job is a molybdenum (moly) disulfide. These lubricants are readily available at most hardware and auto parts stores. The most common household option is 3-in-1 Oil Apply the lubricant to the bolt threads ahead of the nut
The idea is to try to prevent the buildup of heat When installing, you may want to try rotating the nut on 3 revolutions then back one, etc. You must do likewise during removal of the nuts too.
