Delrin: A Superior Material, Which Happens To Be Plastic

Consumer plastics often have a bad reputation for being cheap, unreliable materials. Although that may be true in some cases, not all plastics are created equal. Several high-grade plastics are used in demanding engineering applications, including Delrin acetal resin.

What is Delrin Plastic?

Delrin, also known as acetal resin, is an engineered thermoplastic used in precision parts requiring high wear resistance. Delrin is a popular industrial plastic due to its manufacturability and advantages over other plastics and metals.

Properties of Delrin

Delrin possesses several properties that make it ideal for mechanical applications and the material of choice for metal part replacement:

High strength, stiffness, dimensional stability, and overall durability
Low friction and wear resistance
High fatigue and creep resistance—resists cracks and material deformation from mechanical stress over time
Chemical resistances against fuels and solvents, such as gas
Low moisture absorption, allowing effective operation in wet environments
Temperature toughness

Metal gears turning Delrin is often used to replace metal. Aquor Blue Angled Hose Connector plugged into Deckwash outlet installed on a van Aquor connectors can withstand 200+ pounds of lateral force—they won’t break if you tug on them.

Considering all of these beneficial properties, it’s no surprise that manufacturers use Delrin for various high-load mechanical applications. Here are examples of industrial use cases for Delrin plastics:

Heavy load-bearing gears in vehicles
Fuel system elements
Valve and pump components for gas/oil
Safety restraints
Conveyor belt parts
Medical devices

Bicycle Delrin is the material of choice for plastic gears in e-bike motors.

How Aquor uses Delrin

Aquor selected the heavy-duty plastic to create hose connectors based on its low friction nature, high wear resistance, and effectiveness in wet conditions.

We put our system to the test by having a machine repeatedly plug and unplug our connector under pressure. Aquor connectors can last over 150,000 cycles!

It doesn’t end there… watch this 8,000 pound forklift run over an Aquor connector. Talk about durability!

Great Idea

I had been mulling over how I was going to make my outdoor shower frost free to include speaking with several plumbers who did not know of a solution. I watched a UTube video of a plumbing tech show in Las Vegas and saw that it is what I needed as I have a swim spa and we have below freezing temperatures often in the winter months. Like to shower before and after getting into the swim spa.

This replacement fixed the hammer issue at two spigots that I was experiencing. Though I could not detect any visual difference between existing and new replacement vacuum breaker, once replaced the spigot worked again properly.

Quality Product

We purchased the deck wash unit
After the Annapolis sailboat show. It arrived quickly. It is a very solid well made fitting made of
Stainless steel. I had to enlarge the hole where my prior
Fitting was, but, that was Not a Problem. I love the ease of
Use and the fact that it does not Leak. I would like to see a stainless steel hose nipple as an option so I don’t have to run around trying to find one. Other than that. Love it.

Great product, and fantastic customer service

I bought 2 hot+cold hydrants and 2 V2+hydrants from Aquor, and 3 out of 4 of those worked perfectly but one of the V2's would drip constantly after disconnecting the hose connector. Customer service responded quickly and walked me through some troubleshooting steps to try and dislodge potential debris that might not be allowing the operating rod to close all the way, and after that didn't work, quickly shipped me a warranty unit at no cost. We were under construction, and getting a replacement unit immediately was important, and it arrived within days. Once we removed the "defective" unit, we see that it isn't defective at all but the plumber didn't follow the instructions, and used teflon tape which gummed up the mechanism!

5 stars for Aquor, 10 stars even
1 star for the plumber my GC hired

And my (very constructive) feedback: Aquor should put a large label on the hydrant itself, in both English and (more importantly) in Spanish, stuck to the hydrant in a way that hopefully forces someone to remove and read it before install, reminding them to not use teflon tape and that the o-ring built into the hydrant is sufficient to stop leaks, because nobody will read the manual. And I guess, never trust your contractor and watch everything they do, or... just do it yourself!

Great product. Installed in Sun Valley.

We installed this for a client in Ketchum ID. They love it. It replaced an old pump style exterior hose bib
