Special Notice -- 6351 T6 Aluminum
Alloy Cylinders: |
Effective June 17, 2020 Scuba Center made the decision that we will no longer fill any Aluminum Cylinder made from 6351 T6
Aluminum Alloy. These cylinders have exhibited a history of potential SCL (Sustained
Load Cracking) and / or rupturing. While these cylinders have not been
recalled, this decision was made by Scuba Center with the safety of our staff and
customers as the utmost priority. |

The following is a list of cylinders made of
6351 Alloy that will no longer be filled by Scuba Center: |
All Luxfer Cylinders Manufactured Prior to
June 1988. All aluminum tanks under Special Permit # 6498, 922, 7042,
8107, 8364, 8422. All Kaiser aluminum cylinders (Special Permit #
SP6576 expired). All Norris aluminum cylinders (Special Permit # SP6688

Subject: High-Pressure Gauges sold
between 2012 and 2018
|
Where used:
Sold as a stand-alone product, p/n GB01 Standard Fill Checker,
p/n AC360 Deluxe Fill Checker, p/n AC365 Deluxe Cylinder
Equalizer, p/n AC366 |
How to
Identify: The GB01 HP gauges in question have a black
face card with an outer white scale in psi, and an inner blue
scale in bar They are filled with a clear oil. They have ¼” NPT
threads (Fig. 1). |
The Problem:
In the rare event of an internal leak, the black over-pressure
(OP) relief plug (Fig. 2), located on top, should vent, allowing
excess pressure to escape. It does not in all cases. XS Scuba is
finding that as these over-pressure plugs age; they are becoming
harder. While originally supple and pliable, some that have been
in the field for many years have become hard. In some cases, they
found that the plug had become too hard to properly relieve excess
pressure should there be an internal leak. This can result in the
glass lens shattering outward. |

In the last few years, the dive media,
as well as the Dive Alert Network (DAN), has shined a spotlight on
a potentially hazardous situation where nylon regulator hose
interiors can crystalize, resulting in the possibility of crystals
dislodging and creating an obstruction in the regulator. Miflex,
the largest producer of nylon braided hoses in the world, and XS
Scuba, their North American distributor, want to provide details
on this situation to put minds at ease.
