DEFECTIVE OXYGEN CYLINDER VALVES – SHERWOOD VALVES AND TEKNO OXYGEN CYLINDER VALVES
The oxygen leak is caused by an 870 CGA valve manufacturing defect.
CAUTION — SERIOUS GAS LEAK / FIRE HAZARD
What is the problem?
The Tekno Valve and Sherwood branded 870 CGA oxygen cylinder valves are now manufactured with a rounded edge instead of the radius/chamfered edge that has historically been the industry standard design. The removal of this chamfer affects the proper seating and positive seal when used with the vast majority of oxygen regulators in the U.S. market. The lack of a positive, gas‐tight seal is a serious safety hazard, as it may result in a leak due to the partial sealing on the regulator washers.
What actions are recommended?
1) Conduct an inventory audit, inclusive of cylinders in patient homes, to identify and quarantine all cylinders
with affected valves
2) Immediately discontinue patient use and remove the cylinders from the service
3) Post this notice in all cylinder storage and filling areas
4) Contact your cylinder supplier where you purchased the cylinders for resolution
Many fishermen build homemade bait oxygen systems using used and new medical oxygen cylinders with 870 CGA (Post) valves. These O2 cylinders/cylinder valves are cheap, plentiful and free or maybe a relative was using the O2 cylinder at home and no longer needs supplemental oxygen. Fishermen use commercial grade oxygen in these O2 cylinders for live fish transport.
Please review these alerts. If you have are using oxygen cylinders with 870 CGA oxygen cylinder valves – CONTACT Sherwood and or Tekno immediately. DO NOT USE OXYGEN CYLINDERS WITH THESE DEFECTIVE 870 CGA CYLINDER VALVES.

REFILLING YOUR OXYGEN CYLINDER AT WELDING SUPPLY SHOPS, BAIT SHOPS, TACKLE SHOPS AND DIVE SHOPS IS THE FISHERMAN’S RESPONSIBILITY
A high pressure O2 cylinder is full @ 2200 PSI. Are you paying for a “full fill” or are you paying “full fill” prices for partial “short fill” oxygen cylinders.
Most fishermen really believe they are buying and actually getting a FULL CYLINDER FILL when the refilling attendant fills your O2 cylinder to only 1000 – 1500 PSI and tells you this is the maximum PSI your O2 cylinder holds when it is “full filled” with high pressure oxygen gas. THIS IS HUMBUG DUNG!
A SHORT CYLINDER REFILL is not a “full fill.” Sadly, you are being screwed again and again with pre-planning, intention and with forethought. You are being charged for and paying for a “FULL FILL.” This practice is very common, be aware of this practice every time you hire someone to refill your O2 cylinders and prevent the deception up front before it begins.
Always ask the attendant how many O2 PSI is a “full fill?” And, am I being charged for a “full cylinder fill” of pure oxygen?
Every time you have your O2 cylinder refilled ask these 2 questions before he fills your O2 cylinder.
Then show that attendant/store owner your cylinder operating pressure stamped on the shoulder of your cylinder and why 2200 PSI is a “full fill” for your O2 cylinder. You want a “full fill.” You want and are paying a “full fill” not a partial fill. You want a “full fill” 2200 PSI, that’s what you are paying for.
Do Not Be Shy: It’s always necessary that you tell the attendant you want a full fill (2015 PSI + 200 PSI 10% = 2200 PSI maximum cylinder pressure. 2200 PSI is what you are paying for but you are often getting only a partial fill when you are now watching what’s happening. This is like a traveling carney’s trick you get your dollar.
The cylinder refilling hustlers know that most fishermen that use compressed O2 have absolutely no idea how many PSI his O2 tank holds when full if this is not covered in written operational instructions..
This amounts to only an additional few dollars and change for every short refill, expect hours tank times to be hours shorter before your O2 is depleted and no oxygen negatively affects your bait mortality and quality.
Over a few summer months, “short fills” often go unnoticed, meaningless. Over 1 year your additional cost for cylinder refills will be noticeable after you learn what to watch for with the scam, over 5 years additional O2 cost are clearly excessively high, over the years (decades), the rest of your fishing life the bogus short refilling scam charges will be shocking, may be prohibitive and definitely problematic for the average live baiter trusting that bait shop that refills his O2 cylinders. Short filled cylinders run out of gas within a few hours often resulting in excessive bait mortality and disappointing fishing trips. This is especially serious for fishing guides and commercial fishermen depending on supplemental oxygen for their fish and live bait fish transports.
The wise savvy fisherman that uses oxygen-injection systems should know quickly and recognize this slick sales tactic when he’s getting the royally screwed to the deck with big 15” SS screws at this bait shop, welding supply companies or SCUBA Dive shops. The fisherman should know how many PSI O2 is a FULL CYLINDER FILL for his portable O2 cylinder, full is always 2200 PSI and nothing less. The filling pressure PSI is stamped in the metal on the shoulder of all aluminum and steel O2 cylinders in plain sight for you and the employee refilling you cylinder to see. Charging full fill price for short filled cylinders is intentional, never accidental!
Always trust and be sure you verify you O2 cylinder is “full fill” with employee that actually refills your O2 cylinder. Always attach your O2 regulator to your cylinder valve, turn on the cylinder valve and see for yourself what your regulator pressure gage reads PSI. A “full fill” gage pressure is 2200 PSI.
Verification and confirmation your cylinder is “full filled” is totally the fisherman’s responsibility… Short fills are especially common at bait and tackle shops. The bait shop work ethic and attitude is simple, “catch me if you can and you can only catch me if you know how to recognize “SHORT FILLS” using your oxygen regulator gage.
Most fishermen often pay “full fill” prices for “short filled” O2 cylinders is very common: “Short fills” are 1200 PSI – 2150 PSI is “short filled.” Filling PSI is stamped on the shoulder of every oxygen cylinder and may be safely fill with 10% additional PSI.
What is the maximum filling capacity of your particular size aluminum or steel O2 cylinder?
Look on the shoulder of your O2 cylinder, you will cee many numbers meaning different things. If the pressure stamped on the shoulder is 2016 (with a +sign after 2016), a full Fill is 2016 + 10% or 2200 PSI. If the operating pressure stamped on the shoulder of your O2 cylinder is 2200 with (no + sign after 2200), your particular O2 cylinder’s maximum filling pressure is 2200 PSI. Clearly 1500 PSI is a serious (SHORT FILL) DRASTICALLY REDUCING THE NUMBER OF HOURS AVAILABLE TO TRANSPORT BAIT OR FISH.
