Is Your Gear Too Old? A Guide to Retiring Regulators and BCDs

Scuba diving equipment is incredibly durable. It is built to withstand high pressure, salt water, and the sun. Because of this durability, divers often fall into a false sense of security. We assume that if we rinse it and store it, it will last forever.

However, rubber degrades, plastic becomes brittle, and metal fatigues. There comes a point where “servicing” an item is no longer safe or cost-effective. As a diver, knowing when to retire a piece of gear is just as important as knowing how to use it.

At the 72 Aquatics, we often see gear that looks brand new on the outside but is crumbling on the inside. Here is how to tell if your gear has reached the end of its life.

Regulators: The Heart of Your System

Your regulator is a mechanical marvel, but it is also the most critical piece of life-support gear you own.

The “Obsolete” Factor: The most common reason we have to “fail” a regulator isn’t because it’s broken, but because parts simply don’t exist anymore. Manufacturers eventually stop producing service kits for older models.

  • The Rule: If we can’t get the official manufacturer’s service kit, we cannot safely service the regulator. Using generic O-rings or makeshift parts is a gamble you should never take with your air supply.

Internal Corrosion (Verdigris): You might rinse your regulator faithfully, but moisture can still penetrate the chrome plating over 10 or 15 years.

  • The Sign: If you see green, crusty buildup (verdigris) where the hoses connect to the first stage, it’s a bad sign. This corrosion often eats into the threads of the metal body. Once the threads are compromised, the regulator is essentially a ticking time bomb that could blow an O-ring or hose at depth.

Breathing Effort: Regulator technology has improved massively in the last decade. A top-tier regulator from 1995 often breathes harder than a mid-range regulator from 2025. If you find yourself sucking hard for air at 80 feet, your gear might physically be fine, but technologically, it’s holding you back.

BCDs: The Silent Failure

Buoyancy Control Devices have a finite lifespan, primarily due to the materials used to make them airtight.

The “Crunchy” Bladder: This is the easiest test you can do at home. Fully inflate your BCD orally. Now, squeeze the bladder against your ear.

  • The Sign: Does it sound “crunchy,” like crinkling a potato chip bag? If so, the internal urethane coating is delaminating. This means the bladder is peeling apart from the inside. It will leak, and it cannot be repaired. It’s time for a new BCD.

Fading and Brittleness: Inspect the shoulder straps and pockets. Has the black fabric turned a grayish-brown?

  • The Sign: This is UV damage. If the sun has bleached the fabric, it has also weakened the stitching and the plastic buckles. We have seen old buckles snap simply from the weight of a tank being lifted. If your BCD looks sun-bleached, it’s structurally compromised.

The Slow Leak: Inflate your BCD until the over-pressure valves release. Leave it fully inflated overnight.

  • The Test: If it’s soft in the morning, you have a leak. While valves can be cleaned, leaks in the seams (RF welds) are generally unfixable.

Dive Computers: The “Black Screen of Death”

Electronics and salt water are mortal enemies. Even the best computers have a shelf life.

Screen Bleed: Look closely at your LCD screen. Do you see any black spots or rainbow-colored “puddles” in the corners?

  • The Sign: This is liquid crystal leakage. It will eventually spread across the entire screen, obscuring your depth or time data—potentially mid-dive.

Algorithm Updates: Older computers often use outdated decompression algorithms that are much less conservative than modern standards. If your computer is 15 years old, it might be allowing you to stay down longer than is currently considered safe, putting you at risk if you are diving with a buddy using a modern computer.

Wetsuits: The Compression Factor

Neoprene works by trapping gas bubbles. Over time, and with repeated compression at depth, those bubbles collapse.

  • The Sign: A 5-year-old 5mm suit is often actually a 2mm suit in terms of warmth. If you are shivering on dives where you used to be warm, your suit hasn’t “shrunk”—the neoprene has lost its insulating ability.

The Verdict: “When in Doubt, Check it Out”

Retiring gear doesn’t mean you have to throw it in the trash. Old regulators make great desk ornaments! But they shouldn’t be underwater.

If you are unsure about the age or safety of your equipment, bring it to 72 Aquatics.

  • We can look up the serial number to check for parts availability.

  • We can bench-test your regulator to see if it holds intermediate pressure.

  • We can inspect your BCD bladder for internal decay.

Don’t let a $50 part or an old BCD ruin a $3,000 dive trip. Safety is the ultimate luxury—make sure your gear is up to the task.
