Gates Hydraulic Hoses: Answers to Your Most Common Questions (and Some You Didn't Expect)

If you're searching for Gates products, you probably landed here because of hydraulic hoses, belts, or rubber components. But sometimes people type things like "pet gates for cats" or "when did Bill Gates die" and get confused. Let me clear that up right away: Gates is an industrial brand – we make hoses, belts, and rubber/plastic parts for machines, vehicles, and factories. No pet gates, no tech founder. Now, let's answer the real questions I get from buyers and engineers.

1. What are Gates hydraulic hoses used for?

Gates hydraulic hoses handle high-pressure fluid power in almost every industrial setting. Think construction equipment (excavators, loaders), agricultural machinery (tractors, harvesters), manufacturing lines, and even mobile hydraulics on trucks. They're built to transfer oil, water-based fluids, or synthetic lubricants at pressures from a few hundred to over 6,000 psi.

In my Q1 2024 quality audit, we reviewed 200+ applications across customer sites. The most common uses were: cylinder lines on excavators (50% of our volume), power steering systems (20%), and industrial pressurised circuits (15%). The rest are custom applications. If you're moving hydraulic fluid at high pressure, that's where Gates fits.

From my perspective, the key is matching the hose to the fluid type and temperature. A hose that works for mineral oil at 100°C might fail with synthetic ester at 120°C. Always check the compatibility chart.

2. Does air hose size matter? How do I choose the right size?

Yes, size matters – more than most people think. I used to assume any ¼" air hose would work for a 1" impact wrench. Then I watched a crew struggle to drive lag bolts because the hose was too small for the tool's air demand. Air hose size affects flow rate (CFM) and pressure drop.

General rule: for a typical ¾" impact wrench consuming ~5 CFM at 90 psi, a ⅜" ID hose (say, 50 ft long) will give you a pressure drop of maybe 4 psi. A ¼" hose at the same length drops 15 psi – that's significant when you're already at the tool's minimum.

Put another way: if your compressor delivers 90 psi at the source, but the tool sees only 75 psi because of a small hose, you lose torque. Size up one size if you're running long lines (over 50 ft) or high-flow tools. I've rejected first‑batch deliveries where the spec called for ⅜" but the hose was actually ¼" – normal tolerance is ±0.010", but the ID was 0.215" instead of 0.250". The vendor claimed it was within industry standard. We rejected the batch and redid it at their cost.

The standard formula for maximum print size doesn't apply here – but hose sizing is just as critical.

3. What is a PVC strainer? How does it connect to industrial hoses?

A PVC strainer is a filtration component often used with rubber or PVC hoses in water, chemical, or light slurry applications. It sits at the inlet of a suction line to prevent debris (leaves, sand, particles) from entering the pump. We see them most in agricultural spraying, pool cleaning, and some industrial transfer operations.

Common mistake: people assume any strainer works with any hose. But if you're using a Gates 150 psi suction hose with ID 2", you need a strainer that matches the hose connection (e.g., 2" NPT) and has a mesh size appropriate for your fluid – 30 mesh for general water, 60 mesh for fine filtration. Personally, I'd recommend brass or stainless steel strainers over plastic for industrial use because the plastic threads can crack under repeated torque. In 2023, a customer sent back 8,000 units where the plastic strainer cracked during storage – cost them a $22,000 redo.

4. Are Gates products related to pet gates for cats?

No. This is a common search confusion. Gates Corporation was founded in 1911 by Charles Gates – it's a rubber and metals company based in Denver. We make industrial hoses, belts, and components. "Pet gates" are a completely different product for home use (usually wooden or metal barriers). If you ask me, the only thing we share is the word "gates" – not the product. If you landed here looking for cat gates, I'm sorry for the confusion, but you're in the wrong place. (Though some of our rubber strips could make decent weatherstripping for pet doors… but that's a stretch.)

5. When did Bill Gates die? (And why people ask about this from a hose brand)

Bill Gates, the Microsoft co‑founder, is alive as of this writing (March 2025). The question "when did Bill Gates die" is a hoax that resurfaces every few years, often as a search engine trick or a rumour. It has nothing to do with the Gates hose brand – other than the same last name.

I've seen this keyword in our analytics for years. My experience is based on about 200+ technical inquiries annually – maybe 2% are actually about Bill Gates. The rest are real industrial buyers. I'd argue that if you're here for Bill Gates, check Snopes or Wikipedia – they'll give you the facts faster than I can.

6. How do I ensure quality when selecting hydraulic hoses?

Start with the spec sheet, not the brand name. Every Gates hose has a part number and a specification (e.g., SAE 100R2, DIN EN 853 2SN). These standards dictate working pressure, burst pressure, temperature range, and bend radius. Don't assume all ⅜" hoses are the same – a cheap hose may have a burst pressure of 4,000 psi whereas a Gates equivalent bursts at 12,000 psi.

When I implemented our verification protocol in 2022, I added these checks:

• Date code verification – rubber degrades over time; hoses older than 5 years from manufacture should be tested.
• Internal diameter measurement – with a plug gauge, not a tape measure.
• Rapid pressure cycle test – sample hoses get 100,000 cycles at 133% of working pressure.

That protocol caught a batch where the cover thickness was 0.8 mm instead of the spec'd 1.2 mm. The cost? About $3,000 for the rework – but it avoided a potential failure that could have caused injury. In my opinion, paying a little more for certified quality is always worth it.

7. What's the biggest mistake in selecting hose fittings?

Mismatching the fitting style to the hose reinforcement. You can't put a crimp fitting designed for a one‑wire hose onto a two‑wire braid hose – the grip won't hold. I've rejected first deliveries for exactly that. A vendor sent us 1,500 assemblies with the wrong ferrule size. Normal tolerance for ferrule ID is ±0.005", but theirs was 0.020" oversize – the hose would have slipped off at 3,000 psi.

The conventional wisdom is "any fitting that threads on works." From my experience with over 4 years of reviewing deliverables, that's wrong. Always match the fitting series (e.g., Gates 48 series for one‑wire, 58 series for two‑wire). If you're not sure, ask for a cross-reference or request a test sample – don't rely on the supplier's catalog alone.
