ZDBB 1075 Pcs 3-in-1 Spigot Repair Washers & Hose Gasket & Faucet O-Rings Kit 37 Size Plumbing Rubber Washers Assortment Set for Kitchen Faucet Outdoor Hose Bib Water Spigot Seal Repair

Why I added this kit to my bench

A leaky hose bib on a Saturday morning is an excellent reminder that small rubber parts do an outsized amount of work. I picked up the ZDBB washer and O‑ring kit specifically to stop chasing individual washers and gaskets at the hardware store. After several weeks of using it across a few real repairs—indoor faucets, an outdoor spigot, a pressure washer wand, and a garden hose splitter—I’ve formed a clear picture of where this kit shines and where it doesn’t.

What you actually get

This is a 3‑in‑1 assortment with three distinct groups of parts:

• Spigot/faucet stem washers: 54 pieces in flat and beveled profiles, covering sizes like 3/8, 1/4L, 1/4, 1/4M 0, and 1/4S 00. There are also six brass screws for stem washer replacement.
• Plumbing gaskets: 93 pieces sized for common fittings (outer diameters called out at 1-7/32", 1", 15/16", 14/16", 3/4", 1/2", 23/64"). These address garden hose couplers, shower hoses, sink connections, and washing machine supply lines.
• O‑rings: 916 pieces made from NBR (nitrile rubber) in a useful spread of metric inner diameters: 3, 4, 4.5, 5, 6, 7, 8, 9, 10, 12, 13, 14, 17, 18, 20, 22, 25, and 27 mm.

There’s also an O‑ring pick in the box, which turned out to be more helpful than I expected for coaxing old rings out of recessed grooves without scratching soft metals.

Material quality and why it matters

The O‑rings are NBR, which is the right call for general maintenance. NBR handles oils, fuels, and water well, and it has decent temperature resistance for everyday environments. It’s not an aerospace material and it’s not meant for steam service or brake fluid, but for faucets, hose fittings, air, and oil it’s a solid, durable choice. The spigot washers and gaskets are conventional black rubber; they compress predictably and rebound without permanent set when properly sized and not crushed.

Practical translation: I’m seeing firm, uniform compression when tightening fittings, no “chewing” at the edges, and no cracking after initial use. I lightly lubricate rings with silicone grease during installation, which improves sealing and extends life.

Real repairs I used it for

• Dripping hose bib: A beveled 1/4L stem washer and one of the included brass screws cured a persistent drip at the outdoor faucet. The beveled profile seated nicely against the valve seat and provided a clean shutoff. I lapped the seat lightly while I had it open; if your seat is pitted, no washer will compensate for that alone.
• Garden hose and splitter leaks: The 3/4" gaskets solved a slow leak at the swivel end of a hose and sealed a two‑way splitter that had been misting under pressure. I also replaced a flattened gasket inside a quick‑connect coupler and regained a positive seal.
• Shower hose swap: A 1/2" gasket sealed a replacement handheld shower hose on the first try.
• Pressure washer wand: A 9 mm ID O‑ring fit the nozzle interface on my wand and sealed cleanly after a light coat of silicone grease.
• Sink faucet spout: An 8 mm ID O‑ring replaced a weeping seal on a pull‑out spout, ending a small but annoying drip.

None of these repairs required heat or thread sealant; a correct-size elastomer and a clean mating surface did the job. Everything I’ve resealed has stayed dry since.

Sizing: coverage and selection

There’s good coverage on everyday sizes—especially for hose washers and faucet stem washers—and the O‑ring selection hits many common ID ranges in metric. Plumbing in North America mixes inch and metric dimensions in frustrating ways, but the step sizes here are close enough for most groove geometries I encounter in faucets, hose ends, and small tools.

A few notes on picking sizes:

• O‑rings are specified by inner diameter and cross‑section. If you don’t have calipers, you can match by gently laying the old ring over the candidates and selecting a ring that is slightly smaller in ID (to stretch 2–5%) and equal in thickness.
• Flat vs. beveled stem washers: Use beveled for classic compression valves with conical seats; use flat for flat seats and some cartridge styles. If your valve stem is chewed or your seat is pitted, address that before blaming the washer.
• The “14/16” gasket callout is functionally 7/8"; treat it that way when matching hose couplings.

The kit errs toward breadth rather than multiple duplicates of a few sizes. That’s good for problem solvers who run into oddball fittings; it just means you’ll want to restock high‑turn sizes eventually.

Usability and organization

The assortment is separated by type and size. I appreciate having stem washers, gaskets, and O‑rings in one place; I no longer bounce between three different kits to finish a single repair. The included pick is the right shape to sneak behind an O‑ring without gouging. A tiny tip: wipe a little silicone grease on the pick before removal—it reduces drag and helps minimize nicks on soft brass and plastic bores.

One caution: with this many sizes, it’s easy to mix compartments during a rushed job. I’ve gotten in the habit of opening only the bins I need, and I label the lids on my organizer with a paint pen so I can drop unused parts back where they belong.

Performance and durability so far

Seals compress evenly and hold pressure without needing to over‑tighten. After the initial installations, I checked connections again a week later—no flattening or creep that would suggest poor materials or out‑of‑spec sizing. In the pressure washer wand, the O‑ring has seen multiple heat cycles without hardening. I wouldn’t push NBR into steam service or prolonged high‑temperature zones, but for household water and typical shop fluids, the results have been consistently reliable.

Limitations and what this kit won’t do

• High heat and harsh chemicals: NBR is a generalist. For steam, strong oxidizers, or high‑temperature environments, you’ll want EPDM, FKM (Viton), or PTFE seals.
• Brake systems: If you’re working on hydraulic brakes, use EPDM seals that are compatible with glycol‑based fluids.
• Potable water certifications: There’s no stated NSF/WRAS certification. I’m comfortable using these in garden hoses, outdoor spigots, and downstream faucet points, but I avoid using uncertified elastomers in concealed potable water lines.
• Inch‑specific O‑rings: The O‑ring set is metric‑focused. That’s fine for many appliances and tools, but certain equipment with inch grooves may need a dedicated SAE kit to get perfect cross‑section matches.

Tips to get better, longer‑lasting seals

• Clean the mating surfaces. Mineral scale and burrs defeat new rubber instantly. A Scotch‑Brite pad and vinegar do wonders on brass and chrome.
• Use silicone grease sparingly. A thin film protects rubber, helps installation, and prevents twisting during compression.
• Don’t crank down. If a fresh gasket still leaks, you likely have the wrong size or a damaged seat—not a tightening issue.
• Save one of each used size. I keep a “match sample” bag taped inside the lid so I can grab replacements faster next time.

Who it suits and value

If you maintain your own home, garden gear, or light equipment, this kit earns its drawer space. The mix of stem washers, hose gaskets, and a broad O‑ring selection means most minor leaks get solved in one trip to the toolbox. Pros who do service work will appreciate having a catch‑all on the truck, though specialists may still want material‑specific assortments for high‑heat or chemical exposure.

The inclusion of brass screws and a pick tool means you can replace a faucet stem washer immediately—no extra parts runs. Given the coverage and the count, it’s an economical way to stop paying for single blister‑pack washers that cost more than they should.

Bottom line

I recommend the ZDBB washer and O‑ring kit. It consolidates three separate assortments into one, the NBR rings and rubber washers seal reliably for typical household and outdoor jobs, and the size spread covers the majority of “place where water should not be” problems I see. It’s not the answer for high‑temperature or chemically aggressive situations, and inch‑purists may still want a dedicated SAE O‑ring set, but for everyday plumbing and light equipment repair, this kit has already paid for itself in saved trips and solved drips.
