XBVV 37 Size 1075 Pcs Faucet Washers & O-Rings Kit & Plumbing Gasket 3-in-1 Home Universal Rubber Washers Assortment Kit for Faucet Hose Spigot Plumbing Seal Repair with Pick Hook

Why I added this kit to my bench

I keep a small bin of “consumables” in the shop—things that aren’t glamorous but save jobs: zip ties, thread seal tape, hose gaskets, O-rings. The XBVV washer and O-ring kit earned a permanent spot there after a month of regular use around the house and garage. It’s a dense, no-nonsense assortment: flat and beveled faucet washers, plumbing gaskets, and a very large pile of nitrile (NBR) O-rings, plus a basic pick hook and a handful of brass screws for faucet repair. If you’ve ever burned half a day chasing a single washer size, you’ll understand why having this many options in one box is useful.

What’s inside

• 916 NBR O-rings in 18 sizes
• 10 types of flat and beveled faucet washers (the common 1/4, 1/4L, 1/4M, 1/4S, 3/8, etc.)
• 14 plumbing washers/gaskets spanning typical sink, shower hose, and hose bib dimensions
• 6 brass screws for compression-style faucet washers
• A small pick hook for removing old seals

The counts skew heavily toward O-rings, and that’s fine by me. Most “mystery leaks” I see end up being an O-ring that’s flattened, nicked, or just gone missing.

Build and material quality

All of the O-rings are nitrile (NBR), the workhorse choice for water, oil, and general-purpose sealing. NBR is a practical middle ground: it stands up well to petroleum products and everyday temperatures, doesn’t swell excessively in water, and is affordable enough to stock in bulk. I wouldn’t use these for high-heat applications, strong solvents, or refrigerants—there are better materials like HNBR, FKM, or EPDM for those use cases—but for faucets, hose fittings, pressure washer guns, small engines, and air tools, NBR is exactly what I expect to reach for.

The faucet washers and plumbing gaskets are firm enough to resist splitting but soft enough to seat nicely. The beveled washers in particular compress predictably in older compression faucets. The included brass screws are a nice touch; I’ve had more than one original screw snap from corrosion, and having the correct profile on hand keeps the repair moving.

The pick hook is basic but serviceable. It’s not a professional scribe by any stretch, yet it’s the right size and shape for fishing out hardened O-rings from grooves without gouging mating surfaces—especially helpful in faucet stems and spray wands.

Real-world use

Here’s what I actually fixed with the kit:

• Outdoor spigot and garden hose leaks: The standard 3/4 inch hose gaskets were spot on. I replaced a flattened washer in a Y-splitter and a couple of spray nozzles. The thicker cross-section option solved a stubborn drip at the splitter’s swivel.
• Dripping kitchen faucet (compression type): One beveled washer and a replacement brass screw later, the handle seated smoothly and the drip was gone. I lubricated the stem and new washer with silicone grease during reassembly.
• Bathroom faucet aerator: The tiny flat gasket behind the aerator had hardened. Swapped in a matching washer from the kit; issue solved in 60 seconds.
• Pressure washer gun: The original O-ring on the quick-connect had a nick that was throwing a mist at the joint. One of the smaller NBR rings in the set cured it, and it held up fine through several hours of hot water use.
• Washing machine hose: Replaced one tired inlet gasket. The included plumbing washers covered the standard 3/4 inch size.

Across those jobs, the seals compressed evenly and didn’t cold-flow after a few days under pressure. No telltale weeping, and no need to overtighten fittings to compensate for poor material.

Organization and sizing

The organizer is better than the typical bargain-bin assortment. Compartments keep the families separated, and most cells are labeled by size so you’re not guessing. That said, tiny rings will migrate if you jostle the case; keep it stored flat. I added a piece of painter’s tape across the lid just to be safe.

Sizing is broad where it matters. You get multiple cross-sections for similar inner diameters, which is hugely helpful when you’re replacing a ring where the exact spec is unknown. The faucet washer selection covers common sizes for older and budget fixtures. For modern ceramic cartridge faucets, this kit won’t replace a cartridge, but it will take care of O-rings and spout gaskets around the cartridge.

A small gripe: there’s no printed sizing gauge or chart beyond the compartment labels. I keep a caliper on hand for measuring grooves and washers; if you don’t, expect a bit of trial and error. A simple card with ID/OD/cross-section conversion guidance would make this genuinely beginner-friendly.

Performance and durability

NBR’s sweet spot is the everyday plumbing and shop environment: air, water, oils, and fuels at moderate temperatures. In my pressure washer gun and garden hose fittings, the rings seated cleanly and stayed put. In faucets, the beveled washers sealed reliably without needing to reef down on the handles. After a few weeks, nothing has loosened up or started weeping.

If you plan to tackle:
- Automotive A/C: get HNBR-specific O-rings.
- Brake systems: use EPDM only.
- High-heat or aggressive chemicals: look for FKM/Viton or specialized materials.

That’s not a knock on this kit—it’s simply material science. For 90% of homeowner jobs, these are the right rings and washers to reach for.

Where it falls short

• Limited large-format options: If you regularly service pool equipment or big canister filters, the upper range here may feel limited. You get a nice spread, but not the truly oversized seals.
• All one material: NBR everywhere. I would have loved a small mix of EPDM washers for hot potable water and maybe a few FKM rings for high-heat spots. As-is, you’re getting breadth of size, not breadth of material.
• Organization could be tighter: The case works, but the smallest rings can hop compartments if the box tips. Labels are tiny. Not a dealbreaker—just keep it upright.
• No lubricant included: Silicone grease extends seal life and makes installs easier. I consider it essential; add a small tube to the case and you’re set.

Value

The value proposition is strong. Buying individual faucet washers and hose gaskets at a hardware store adds up quickly, and that assumes the store stocks the odd sizes you need. This kit paid for itself the first weekend I used it: no extra trips, no halfway fixes, and I still have more seals than I’ll likely use in a year. For homeowners and light-duty pros, it’s a sensible, cost-effective inventory to keep on hand.

Who it’s for

• Homeowners who want to fix drips and leaks without hunting down single washers
• DIYers working on small engines, air tools, and pressure washers
• Maintenance folks who need an all-around seal kit for common repairs
• Landlords or facility managers who want a grab-and-go box for faucets and hoses

Not ideal for: automotive HVAC techs, brake specialists, or anyone who needs high-temperature or specialty chemical compatibility.

Tips for success

• Keep a caliper in the case. Measure the groove ID and width when possible.
• Lightly grease O-rings and faucet washers with silicone grease before installation.
• Replace compression faucet screws if they’re corroded; don’t force them.
• Store the case flat. If you travel with it, add a strip of tape across the lid.

Final take

The XBVV washer and O-ring kit is a practical, well-stocked assortment that covers the leaks and squeaks most of us face: faucets, hose fittings, spray wands, and the oddball O-ring inside a tool you forgot had one. The NBR material is appropriate for everyday water, oil, and air service. The included faucet washers and brass screws make it genuinely useful for older compression faucets, not just “O-ring only” repairs. Organization is good enough, quantity is generous, and the pick hook—basic as it is—makes seal removal far less frustrating.

Recommendation: I recommend this kit for homeowners, DIYers, and maintenance techs who want a reliable, broad-coverage seal assortment for general plumbing and light mechanical work. It’s not a specialty materials kit, and it doesn’t fully cover oversized seals, but for the common fixes you’ll encounter monthly, it earns its space on the shelf and pays for itself quickly.
