Catilon PK1100 Brass Globe Valve Faucet Stem Assy and PP806-15 Broach Sillcock Tee Hose Bibs Handle Compatible with Arrowhead Hose Bibs, Boiler Drains & Sill Faucets

What it is and why I tried it

I picked up the Catilon stem and handle kit to refresh an older Arrowhead hose bib on a rental property that had developed a slow drip and a stubborn, crusty handle. Rather than pulling the entire faucet body, I wanted a quick internal rebuild: new stem, new washer, and a clean handle that would give predictable shutoff. On paper, this kit checked those boxes—solid brass stem, a metal tee handle, and compatibility with Arrowhead’s one-piece bonnet style globe valves you commonly see on hose bibs, sillcocks, and boiler drains.

Build and materials

The stem is solid brass, which is what I expect for a traditional globe valve. Brass threads feel secure, resist galling, and stand up to mineralized water better than pot-metal bits. At the sealing end, the stem uses a fixed rubber washer to compress against the valve seat. That’s the classic, serviceable design that’s easy to understand and maintain.

The included tee handle is metal with a corrosion-resistant finish. It isn’t flashy, but it’s sturdy, and the broach fit on mine was snug with no wobble. The coupe of things worth noting:
- The kit includes both the PK1100-style brass stem assembly and a PP806-15 broach tee handle.
- The stem is not internally threaded at the handle screw hole from the factory. You’ll either need to tap it or let the handle screw self-tap threads during installation. More on that below.

Overall, the parts feel like real service components rather than decorative replacements. Edges are clean, threads are cut well, and the washer is centered and seated squarely.

Installation experience

On my Arrowhead hose bib with a one-piece bonnet, install time was under 20 minutes, including cleanup. Here’s how it went.

1) Shut off water to the line and open the faucet to relieve pressure.

2) Remove the handle and packing nut/bonnet. Extract the old stem.

3) Inspect the valve seat inside the body. Mine had light mineral buildup but no deep pitting. A quick clean with a cloth and a seat pick to remove deposits was enough.

4) Apply a small amount of plumber’s grease to the new stem threads and the packing area.

5) Slide in the new stem assembly, reinstall the bonnet/packing nut, and snug it.

6) Install the handle.

Two small but important notes:
- Handle screw threading: Because the stem wasn’t pre-threaded, I used the existing screw as a self-tapper. It bit cleanly and formed threads without drama. If your screw feels mushy or is out of alignment, stop and use an actual tap to start threads so you don’t cross-thread the stem.
- Nylon washer caution: There’s a nylon component at the top of the stem stack-up. If you reef down on the handle screw, you can deform it. Tighten just until the handle is secure and there’s no play—then stop.

After reassembly, I cracked the supply back on, closed the faucet, and checked for leaks. A minor weep at the packing nut disappeared with an eighth-turn snug.

Performance and feel

Once seated, the faucet closed positively and the persistent drip was gone. The turning action felt smooth with appropriate resistance—what you expect from a proper globe valve with fresh packing and a new washer. The tee handle offers good leverage and is easy to grip with wet or gloved hands.

Water control is predictable. You get fine adjustment from trickle to full flow as you turn the stem, and the shutoff point is crisp. If you’re coming from a worn stem where you had to over-torque to stop a drip, this is a nice reset back to how the faucet should behave.

Compatibility notes and fit

This kit is aimed at Arrowhead-style hose bibs, sill faucets, and boiler drains using a one-piece bonnet configuration. On my Arrowhead sillcock, the broach and bonnet geometry matched, and the stem length was appropriate for full travel without bottoming prematurely. If you’re not certain about compatibility:
- Verify your bonnet style (one-piece vs multi-part).
- Check that your handle’s broach profile matches the PP806-15 style. The included handle fit tightly on mine with no slop.
- Inspect the valve seat. If the seat is deeply pitted or cracked, a new stem alone won’t solve leaks; you may need to reface or replace the seat.

I wouldn’t assume compatibility with frost-free stems that have different travel and shutoff points unless you know your specific Arrowhead model uses a comparable stem and seat arrangement. This kit is for traditional globe-style shutoffs at the body, not quarter-turn ball valves.

Durability and maintenance

Brass stem, metal handle, and a straightforward washer/seat interface are all long-term serviceable components. The biggest wear item here is the rubber washer. It’s easily replaceable down the road, and because it’s a fixed washer design, you can swap it with a standard sized washer if needed.

A couple of maintenance pointers:
- If you notice a small drip months or years later, try a slight snug on the packing nut before tearing it back apart. That’s often enough to restore seal in the stem packing area.
- Keep a light coat of plumber’s grease on the stem threads during service to maintain smooth operation and protect against corrosion.
- Avoid aggressive over-tightening at shutoff; firm is fine. Over-torque accelerates seat wear and deforms washers.

After installation, I ran the faucet daily for a week and did multiple pressure cycles with a hose and nozzle. No seepage at the stem, no packing leaks, and the handle stayed tight.

Where it excels

• Quick rebuild for leaky Arrowhead hose bibs: If your leak is due to a worn washer or tired stem packing, this kit provides a clean fix.
• Solid materials: Brass stem and a metal handle inspire confidence and should outlast cheaper die-cast options.
• Straightforward serviceability: Traditional washer/seat design is easy to understand and maintain.

What could be better

• No internal threading at the handle screw hole: The self-tap approach works, but it adds a step and introduces a chance for cross-threading. Pre-threading at the factory would eliminate the guesswork.
• Minimal guidance: An included one-page instruction sheet with torque guidance for the packing nut and a clear “do not overtighten” warning for the nylon washer would help less experienced DIYers.
• Finish options: The handle’s finish is functional but utilitarian. Not a deal-breaker for an outdoor faucet, but worth noting.

Practical tips for a successful install

• Before you buy, shine a light into the faucet body and inspect the seat. If it’s badly pitted, plan on a seat dressing or replacement to guarantee a drip-free result.
• Use plumber’s grease on threads and packing; use PTFE tape sparingly where appropriate, but avoid introducing tape into the valve body where it could shed.
• Let the screw self-tap slowly and keep it square. If resistance spikes, back out and re-start—or tap the hole properly.
• After pressurizing, tighten the packing nut in tiny increments. Many “packing leaks” vanish with a very small adjustment.

Value and who it’s for

If you’ve got an Arrowhead hose bib, sillcock, or boiler drain that’s dripping or feels gritty and inconsistent, this kit offers a cost-effective refresh without replacing the entire faucet. It’s particularly well-suited to homeowners and maintenance pros who are comfortable with light mechanical work and understand the basics of valve service.

If you need absolute plug-and-play with zero fiddling or you’re dealing with a frost-free faucet whose shutoff is far back in the wall, verify compatibility carefully or consider a full faucet replacement.

Recommendation

I recommend the Catilon stem and handle kit for owners of Arrowhead-style hose bibs and sill faucets who want a durable, serviceable fix for leaks and sticky operation. The brass stem and metal handle deliver solid performance, the sealing washer does its job, and installation is straightforward for anyone with basic tools. Be aware of the unthreaded handle screw hole and take care not to overtighten against the nylon washer. With those caveats in mind, it’s a practical, reliable upgrade that restores proper function without replacing the entire faucet.
