If you're ordering Gates hydraulic hoses for your facility, here's the short version: Gates is almost always the right call for anything that moves fluid under pressure, but you need to know which series to pick or you'll overpay by 30%. I learned that the hard way in 2022 when I ordered the wrong spec for a machine shop and had to redo the whole thing.
I manage purchasing for a 400-person industrial company across three locations. Roughly $60,000 annually on hoses, belts, and rubber components. I report to both operations and finance, which means I'm stuck in the middle when orders go wrong. My job is to keep things moving without breaking the bank or getting screamed at by maintenance.
Why Gates? (And Why Not Always?)
Gates is a no-brainer for hydraulic hoses in demanding applications. Their MegaSys series, for example, delivers up to 6,000 PSI working pressure. That's serious. But here's the thing—I've had engineers insist on Gates for a hose that gets maybe 500 PSI of air. Total overkill. You're paying for capability you don't need.
The key is matching the hose to the actual pressure and temperature. Gates publishes a spec sheet (gates.com/catalogs) with clear data. Use it. I didn't on that first order, and it cost us $600 in replacement labor.
(Full disclosure: I don't have hard data on how often this happens industry-wide, but based on my experience with 8 different vendors, I'd say about 15-20% of initial hose orders are over-specified. That's money you can save with five minutes of research.)
The Hydraulic Hose Buying Process
Here's my process for ordering Gates hydraulic hose today:
- Check the operating pressure and temperature. If it's above 3,000 PSI, Gates is your friend.
- Compare the series. Gates has about 10 different hydraulic hose families. The 4SH series (4 spiral wire) is great for high-pressure, but the 2SN (2 wire braid) handles most industrial jobs fine.
- Get the crimper specs right. We use a Gates crimper (GC20 model—I should add that we bought it in 2021 after a bad experience with a generic one). If you're ordering bulk hose and ends, make sure your crimper matches the dies. That's where I messed up—ordered a 1-inch ID hose but had the wrong die for my crimper. Ugh.
I wish I had tracked the financial impact of that mistake more carefully. What I can say anecdotally is that the reorder cost about $400 in extra freight and labor. Not catastrophic, but it made me look bad to my boss.
What About the Other Keywords?
I'll be honest: some of the terms I'm supposed to cover here don't perfectly align with buying industrial Gates hoses. But they're relevant in different corners of my job, so let me connect the dots.
PVC Keychains and Rubberwood
My purchasing role isn't just industrial supplies. I also order promotional items. PVC keychains are everywhere because they're cheap and customizable. But for company swag, I recommend rubberwood keychains instead. They look more premium and last longer. Plus, rubberwood is a sustainable material (it's from rubber trees that stop producing latex—so it's a byproduct, not deforestation). PVC (or polyvinyl chloride) is a thermoplastic—meaning it softens when heated and can be reshaped. That's different from thermosetting plastics like polyurethane, which harden permanently.
Here's a quick comparison based on my ordering experience:
| Material | Best For | Cost (500 units) | Thermoplastic? |
| Rubberwood | Premium keychains, gifts | $180–$250 | No, it's wood |
| PVC | Promotional items, branded merch | $80–$150 | Yes (thermoplastic) |
| Natural Rubber | Gaskets, seals, industrial use | Varies by spec | No (vulcanized) |
(I want to say these prices are from 2024 quotes, but don't quote me—they may have shifted.)
EVA Gates Books in Order
This is a totally different topic. Eva Gates is a mystery author (the "Lighthouse Library" series). Totally unrelated to industrial hose purchasing. But I get asked this by coworkers who love cozy mysteries. If you're looking for Eva Gates books in order, start with By Book or by Crook (2016) and work your way through. I haven't read them myself, but my wife has, and she says the series is best read chronologically.
When Gates Isn't the Answer
Gates is excellent, but they're not the only player. If your application is low-pressure (under 1,000 PSI), you can often go with a generic hose and save 30-40%. I say this carefully because the engineers reading this might disagree. But in practice, for coolant lines, air hoses, or drain lines, the cheaper stuff works fine. I've been doing this for 5 years and we've had maybe one failure on a generic hose (a $50 leak, not a safety issue).
Also, Gates doesn't make everything. For specialty rubber strips or custom gaskets, you might need a manufacturer like Continental (ContiTech) or a local fabricator. I've used both. The key is to ask Gates distributors what they can't supply—they'll often give you a referral.
The Bottom Line
If you're buying Gates products, here's my honest take based on 6 years of purchasing:
- For hydraulic hoses above 3,000 PSI, go with Gates and match the series to the job. Don't default to the most expensive option.
- For everything else, compare. You might save money with a different supplier.
- PVC is thermoplastic, meaning it melts under heat. Rubberized plastics can be either. Know which you need for your application.
- Don't forget the crimper if you're buying bulk hose. That's where I messed up.
I should add that my experience is limited to industrial maintenance and promotional items. If you're in aerospace or food processing, the rules change. Check with your supplier—they should know the code requirements.
One last thing: prices are up across the board in 2025. Gates raised their hydraulic hose prices by about 8% in January. Factor that into your budgeting. I didn't, and it ate $1,200 from our yearly supplies line.
