Ever had a faucet leak or needed to shut off water fast—but your old valve squeaked, stuck, or worse, leaked? You’re not alone. Millions of homeowners and plumbers face plumbing frustrations daily. That’s where the Eastman Speed-Flex 1/4 Turn Angle Stop Valve Plumbing Supply shines: a modern, quarter-turn shutoff that delivers speed, durability, and peace of mind. Whether you’re renovating, repairing, or upgrading, this valve might be your new best friend under the sink.
What Is the Eastman Speed-Flex 1/4 Turn Angle Stop Valve?
An angle stop valve (also known as a “fixture shutoff valve”) controls water flow to individual fixtures like sinks, toilets, or washing machines. Unlike traditional multi-turn valves that require 3–5 full rotations to close, the Eastman Speed-Flex uses a 1/4-turn ceramic disc mechanism, letting you stop water flow instantly with a quick flick of the handle.
Designed for both residential and light commercial use, it’s part of Eastman’s premium plumbing line—engineered for longevity, corrosion resistance, and easy installation.
💡 Did You Know? According to the EPA, household leaks waste nearly 1 trillion gallons of water annually in the U.S. alone. A reliable shutoff valve like the Speed-Flex can prevent costly water damage before it starts.
Why Choose Eastman Speed-Flex Over Traditional Valves?
Many older homes still use compression-style or multi-turn gate valves, which wear out faster and are prone to mineral buildup. Here’s how the Speed-Flex stands out:
✅ Key Advantages:
- 1/4-Turn Operation: Shut off water in a split second—critical during emergencies.
- Ceramic Disc Technology: Resists wear, scaling, and corrosion far better than rubber washers.
- Lead-Free Brass Construction: Meets NSF/ANSI 61-G and NSF/ANSI 372 standards for safe drinking water.
- Speed-Flex Fitting: Allows 360° rotation after installation, making it ideal for tight spaces under sinks.
- Compatible with PEX, Copper & CPVC: Works with most common plumbing systems without adapters.
⚠️ Traditional Valve Drawbacks:
- Prone to “packing nut” leaks
- Handle corrosion or breakage
- Require multiple turns (slower response)
- Limited flexibility in cramped installs
For visual comparison:
| Feature | Eastman Speed-Flex | Traditional Multi-Turn Valve |
|---|---|---|
| Operation | 1/4 turn | 3–5 full turns |
| Material | Lead-free brass + ceramic disc | Brass + rubber washer |
| Space Flexibility | 360° rotating outlet | Fixed angle |
| Lifespan | 10–20+ years | 5–10 years (with maintenance) |
| Leak Risk | Very low | Moderate to high over time |
How to Install the Eastman Speed-Flex 1/4 Turn Angle Stop Valve (Step-by-Step)
Installing this valve is beginner-friendly—especially if you’re replacing an old one. Here’s a clear, safe guide:
Tools Needed:
- Adjustable wrench
- Pipe cutter (if switching from copper)
- PEX crimp/clamp tool (if using PEX)
- Teflon tape or pipe thread sealant
Installation Steps:
- Shut Off Main Water Supply
Locate your home’s main water shutoff (usually in the basement or utility room). Turn it off completely. - Drain Residual Water
Open the nearest faucet to release pressure and drain remaining water from the line. - Remove Old Valve
Use a wrench to disconnect the supply line and unscrew the old valve from the wall stub-out. Clean threads if reusing copper. - Prepare New Valve
- For copper pipes: Wrap male threads with Teflon tape (3–4 wraps clockwise).
- For PEX: Slide crimp ring onto PEX tube, insert into Speed-Flex PEX inlet, then crimp with tool.
- For CPVC: Use solvent cement per manufacturer specs.
- Attach the Speed-Flex Valve
Hand-tighten first, then use a wrench for 1/4 to 1/2 turn more—do not overtighten, as this can crack fittings. - Connect Supply Line
Attach your faucet supply line to the 3/8″ compression outlet. The rotating feature lets you align it perfectly without twisting the line. - Turn Water Back On & Test
Slowly open the main supply. Then open the Speed-Flex valve fully and check for leaks at all connections. Let it run 1–2 minutes to flush debris.
🔧 Pro Tip: Always open the valve fully during normal use. Quarter-turn valves are designed to be either 100% open or 100% closed—partial positions can cause turbulence and premature wear.
Real-World Performance: What Plumbers & Homeowners Say
In a 2024 survey by Plumbing Contractor Magazine, 87% of licensed plumbers ranked Eastman’s Speed-Flex among their top 3 preferred angle stops for residential jobs. One contractor in Austin, TX, reported:
“I’ve installed over 200 Speed-Flex valves in the last two years. Zero callbacks for leaks or handle failure. That rotating outlet? Game-changer in pedestal sink installs.”
Similarly, Home Depot and Lowe’s consistently rate this valve 4.7+ stars (based on 5,000+ reviews), with users praising its “smooth action” and “no-drip reliability.”

Common Applications for the Eastman Speed-Flex Valve
This valve isn’t just for kitchen sinks. It’s versatile across fixtures:
- Bathroom vanities (hot & cold lines)
- Toilets (replacing old ballcocks or worn shutoffs)

Its compact size (typically 2.5″ x 1.5″) fits even in ultra-tight cabinet spaces—especially useful in condos or retrofits.
FAQ Section
Q1: Is the Eastman Speed-Flex valve lead-free?
Yes. It complies with the U.S. Safe Drinking Water Act and is certified lead-free (<0.25% weighted average) under NSF/ANSI 372—safe for potable water lines.
Q2: Can I use it with PEX-A, PEX-B, or PEX-C tubing?
Absolutely. The Speed-Flex uses a universal PEX connection compatible with all PEX types when used with proper crimp or clamp rings (ASTM F877/F2023 compliant).
Q3: What’s the maximum pressure and temperature rating?
Rated for 200 PSI at 180°F (82°C)—well above typical residential water pressure (40–80 PSI) and safe for hot water lines.
Q4: Does it come with a warranty?
Eastman offers a limited lifetime warranty against manufacturing defects for the original purchaser—proof of their confidence in durability.
Q5: Why does my handle only turn 90 degrees? Is that normal?
Yes! That’s the defining feature of a 1/4-turn valve. It goes from fully open (handle parallel to pipe) to fully closed (handle perpendicular) in 90°. Don’t force it further—that could damage the ceramic disc.
Q6: Can I install it horizontally or upside down?
Yes. Unlike older gate valves, the Speed-Flex works in any orientation—vertical, horizontal, or even inverted—thanks to its sealed ceramic cartridge.
