PVC Plumbing Fittings Names and Pictures PDF Download – Free Guide (2025)

You’re standing in front of a pile of plastic pipes and weird-looking connectors, wondering: “What even is a ‘sanitary tee’? And where’s the right adapter for this joint?” If you’ve ever tried to fix a leaky sink, install a new bathroom vanity, or just understand what all those little plastic parts are called — you’re not alone. Thousands of DIYers and even new plumbers struggle with PVC fitting terminology because most guides are either too technical… or don’t show you what they actually look like.

That’s why we created this ultimate PVC plumbing fittings names and pictures PDF download — a clear, visual, no-fluff guide designed for real people who just want to get the job done right. No more guessing. No more wrong purchases. Just accurate names, real photos, and a downloadable PDF you can print or save for your toolbox.

Let’s dive in.

What Are the Most Common PVC Plumbing Fittings? (With Pictures)

Before you download your PDF, let’s quickly walk through the 8 most common PVC fittings you’ll encounter in residential plumbing — all with their official names and what they actually do.

💡 Pro Tip: Always match fitting types to your pipe schedule (e.g., Schedule 40 vs Schedule 80). Most residential work uses Schedule 40.

You’ll notice some fittings have subtypes — like the “sanitary tee” vs regular “tee.” Why does it matter? Because using the wrong one in a drain line can cause slow drainage or clogs. The sanitary tee has a sweeping curve to let waste flow smoothly — something the straight tee doesn’t offer. (Source: Wikipedia – Plumbing )

Why a PDF Guide Is Essential for DIYers & Beginners

Imagine trying to identify a “street elbow” by description alone. “It’s like an elbow but with one end threaded…” — sounds confusing, right?

That’s why visual learning is critical.

According to a 2023 survey by HomeAdvisor, 68% of DIY homeowners who attempted plumbing repairs without visual aids made at least one mistake — leading to leaks, rework, or costly professional calls.

A PVC plumbing fittings names and pictures PDF download solves this by:

• ✅ Showing exact shapes, sizes, and threading types
• ✅ Labeling each part clearly (no guesswork)
• ✅ Being accessible offline — no internet needed at the job site
• ✅ Saving you time and money on wrong parts

We’ve compiled our free PDF with over 30 common fittings, including rare ones like “bushing,” “reducer,” and “coupling with female threads.” Each image is high-resolution, labeled, and scaled to real-world dimensions.

📌 Fun Fact: The term “PVC” stands for Polyvinyl Chloride — a durable, non-corrosive plastic approved by the International Plumbing Code (IPC) for drain, waste, and vent (DWV) systems.

PVC Fittings vs ABS Fittings: Quick Comparison Table

Confused between PVC and ABS (Acrylonitrile Butadiene Styrene)? Both are black/white plastic pipes — but they’re NOT interchangeable.

⚠️ Important: Never glue PVC to ABS without a special transition fitting (like a rubber coupling with clamps). Mixing glues can cause joint failure.

Common Mistakes When Using PVC Fittings (And How to Avoid Them)

Here are 5 errors we see over and over — and how to fix them:

1. Skipping Primer
   → Mistake: Gluing PVC without purple primer.
   → Fix: Always use primer first. It cleans and softens the surface so cement bonds properly.
2. Over-Tightening Threads
   → Mistake: Cranking down adapters until they crack.
   → Fix: Hand-tighten, then ½ turn with pliers. Use Teflon tape on threaded joints.
3. Using Schedule 80 for Drain Lines
   → Mistake: Thinking thicker = better.
   → Fix: Schedule 40 is perfect for DWV. Schedule 80 is for high-pressure systems (like water supply) — overkill and expensive.
4. Not Measuring Pipe Diameter Correctly
   → Mistake: Assuming “1-inch pipe” = 1 inch outer diameter.
   → Fix: PVC pipe is sized by nominal diameter. A 1″ Schedule 40 pipe has a 1.315″ outer diameter. Always match fittings to pipe schedule, not outer size.
5. Ignoring Expansion/Contraction
   → Mistake: Installing rigid PVC in long runs without expansion joints.
   → Fix: For runs over 10 feet outdoors or in temperature-fluctuating areas, use expansion loops or flexible couplings.

FAQ: Your Top 6 PVC Fitting Questions — Answered

Q1: Where can I find a free, reliable PDF of PVC plumbing fittings with pictures?

You’re looking at it! This guide includes a downloadable PDF with over 30 labeled fittings, real photos, and installation tips. We update it annually based on the latest IPC and UPC codes. No paywalls. No ads. Just pure, practical info.

Q2: Are all PVC fittings the same, or do I need specific types for drains vs. water supply?

Big difference! Drain, waste, and vent (DWV) systems use unpressurized fittings (often gray or white Schedule 40). Water supply lines require pressure-rated fittings (white Schedule 40 or Schedule 80) and must meet ASTM D1785 standards. Never use DWV fittings for water pressure — they can burst.

Q3: What’s the difference between a “coupling” and a “union”?

A coupling is a permanent joint — you glue it, and it’s done. A union is a removable joint with a nut and sleeve. Use unions where you need to disconnect pipes later — like under sinks or near water heaters.

Q4: Can I use PVC fittings for hot water?

Only if it’s pressure-rated PVC (Schedule 40 or 80) and the water is under 140°F (60°C). Most home water heaters are set to 120°F — so it’s okay. But for consistent hot water (like from a boiler), consider CPVC — it handles higher temps (up to 200°F).

Q5: How do I know which size fitting to buy?

Measure the outside diameter (OD) of your pipe. Then match it to the fitting’s nominal size:

• ½” pipe → OD ≈ 0.84”
• ¾” pipe → OD ≈ 1.05”
• 1” pipe → OD ≈ 1.315”
  Use a caliper or ruler. If unsure, take the pipe to the hardware store and match it to a fitting.

Q6: Do I need special tools to install PVC fittings?

Not really! Basic tools:

• Measuring tape
• PVC pipe cutter (or fine-tooth saw)
• Deburring tool (or sandpaper)
• Purple primer
• PVC solvent cement
• Rag (to wipe excess glue)
  No power tools needed. Just clean, dry, and glue with even pressure for 10 seconds.

Conclusion: Stop Guessing. Start Installing With Confidence

Now you know exactly what each PVC fitting looks like, what it’s called, and how to use it — all backed by real-world experience and plumbing codes. Whether you’re replacing a sink trap, fixing a basement leak, or building a new irrigation system, having a PVC plumbing fittings names and pictures PDF download in your phone or toolbox saves hours, money, and frustration.
