JUNHOME 3 Pack garden hose caps with Washers, Brass Spigot Cap, 3/4" GHT Female End Cap spigot cap hose brass garden hose cap outdoor faucet cover

Why I keep a few brass caps in my hose drawer

Years of wrangling garden hoses, winterizing outdoor spigots, and chasing down mystery drips taught me a simple truth: a good cap solves a lot of small water problems. I’ve been using the JUNHOME brass caps for the past season on a mix of garden hoses, hose bibs, and a couple of drain valves, and they’ve earned a permanent spot in my kit.

What you’re getting

This set includes three 3/4-inch female garden-hose-thread (GHT) caps made from solid brass, six flat rubber washers, and a small roll of PTFE tape. The caps are standard GHT, so they’ll fit any common 3/4-inch male hose thread found on garden hoses, hose bibs, boiler and water heater drain valves, and many RV water fittings. They are not 3/4-inch NPT (pipe thread), which is worth calling out because that confusion causes a lot of mismatched connections. If your fitting says “MHT” or is a standard garden hose connection, these will fit.

Build and design

The first thing I noticed is the weight—each cap feels substantial in the hand. The brass is evenly machined with clean, burr-free threads that catch easily and spin on without fighting the fitting. The hex profile is a practical touch; six flats give you the option to snug or loosen with a wrench if space is tight or a fitting is stubborn. Hand-tight has been enough for me in most cases, but I appreciated the wrench flats when removing a cap that I’d over-tightened during winterization.

Brass is the right material for this job. It resists corrosion outdoors, won’t crack like plastic in the cold, and it holds its shape over repeated tightening. After months of use outside—including some wet/dry cycles and a few frosty mornings—the caps have picked up the mild, expected dulling that brass gets, but no flaking, no pitting, and no sticking to the mating threads.

The washers included are simple flat rubber gaskets. They seat squarely in the cap and compress evenly against mating faces. Having six in the pack is smart; I replace washers on sight when I see a drip starting and it’s nice not to hunt for spares.

Setup and fit

Installation is quick:

• Drop a washer into the cap (one per cap).
• Thread the cap onto the male fitting by hand.
• Snug it down until the leak stops; in most cases that’s a firm hand-tight.

The PTFE tape in the pack is tiny but usable. For hose threads, tape isn’t strictly necessary because the seal happens at the washer, not the threads. I used tape on a couple of older, nicked fittings and it helped the cap seat without weeping. On fresh, clean threads, the washer alone did the job.

On every fitting I tried—standard hose bibbs, a boiler drain, soaker hose ends, and an inline RV filter—the caps engaged smoothly and sealed as expected. The thread engagement is generous enough that cross-threading wasn’t an issue, provided I started straight and didn’t rush.

In use

Here’s where these caps earned their keep:

• Stopping a slow drip at a hose bib I’ll replace later. The cap and washer halted the drip completely without needing to over-tighten.
• Winterizing outdoor spigots. After shutting off the interior valve and draining down, I capped the exterior bibbs to keep out windblown debris and bugs through the off-season.
• RV hose management. Capping both ends of my potable hose keeps the threads clean and prevents the last ounce of water from dribbling into the storage bin.
• Soaker hose ends. The brass caps replaced a couple of tired plastic end caps that had started weeping; the heavier brass sealed instantly and survived a few accidental bumps with a wheelbarrow.
• Boiler/water heater drains. Many of these valves have standard hose threads. A cap is a quick insurance policy if a gate doesn’t fully seat.

Across those tasks, I didn’t see any leakage when the washer was in good shape and the fitting face was clean. If you do see a weep, check the mating face for dents or corrosion, swap in a fresh washer, and tighten a touch more. The hex flats make that last step easy if the cap is tucked near siding or behind a pipe.

Durability and maintenance

I can’t fast-forward years into the future, but brass hardware like this tends to age well if you avoid cross-threading and grit buildup. The most common failure point on caps is the washer, not the body. Keep a couple of washers in a small bag with the caps and you can refresh a seal in seconds. If you store your hoses for winter, take the caps off, shake out trapped water, and stow them dry; rubber lasts longer that way.

The caps didn’t seize on me even after weeks outdoors. If you’re in a coastal environment or you habitually over-tighten, a faint smear of silicone grease on the washer—not the threads—keeps things moving smoothly and improves sealing without encouraging over-torque.

Where these caps shine

• Versatility. Anywhere there’s a 3/4-inch male hose thread, these will fit: hose bibs, garden tools, drain valves, RV lines, and makeshift manifolds.
• Reliable sealing. The combination of clean threads and fresh washers stopped drips reliably in my tests.
• Build quality. Solid brass and a hex profile are the right choices for a part that may live outdoors and occasionally need a wrench.
• Value. Three caps plus six washers and tape cover multiple projects now and leave spares for later.

What could be better

• The PTFE tape roll is tiny. It works in a pinch, but if you use tape regularly, keep a full-size roll on hand.
• Over-tightening can make removal harder. That’s not unique to these caps, but it’s worth a reminder: snug, don’t crank. Use the hex flats and a light touch if you need to nudge them free.
• Not for pipe threads. Again, not a flaw, just a compatibility note. If you’re trying to cap 3/4-inch NPT, you need a pipe cap, not a hose-thread cap.

Practical tips

• Start hand-tight. If it still weeps, replace the washer before reaching for a wrench.
• Clean the mating face. A nicked or dirty seat is the enemy of a good seal.
• Label a cap “potable” if you use it on drinking-water hoses, and keep that one separate from yard duty.
• Keep one in your winterization kit. It’s an easy fix for surprise drips when you shut things down for the season.

The bottom line

The JUNHOME brass caps do exactly what I want from this type of fitting: they fit correctly, seal reliably, and hold up to outdoor use without fuss. The machining is tidy, the hex flats are genuinely useful, and the inclusion of extra washers means you can refresh seals without a hardware run. I’ve used them to stop drips, keep debris out of hoses and filters, and tidy up systems I don’t access often. They’ve been uneventful—in the best way.

Recommendation: I recommend these brass caps to anyone who maintains hoses, outdoor spigots, or hose-thread drain valves and wants a durable, no-drama solution. They’re a meaningful upgrade over plastic caps, versatile across garden and light plumbing tasks, and the three-pack with spare washers is a smart, cost-effective bundle. As long as you’re capping hose threads (not pipe threads) and you resist the urge to over-tighten, they’re a simple tool that solves a lot of small problems well.
