Genuine Replacement
Back in action without the guesswork
A cracked or missing cap turns a working foam cannon into dead weight. This genuine MJJC cap threads straight onto the Foam Cannon Pro bottle with the correct pitch and seal geometry - no modifications, no makeshift fixes.
Why It Matters
Small part. Big impact on your workflow.
Four reasons to keep a spare cap in your kit.
-
Exact OEM Fit
Genuine MJJC part - threads align perfectly with the Foam Cannon Pro bottle, no leaks at the join.
-
Chemical Resistant
Rated for alkaline pre-washes and acidic fallout removers without cracking or degrading.
-
Ribbed Grip Design
Textured outer profile gives you purchase with wet hands or nitrile gloves during a wash.
-
Leak-Free Seal
Maintains proper bottle pressure so the lance draws solution consistently every time.

Built for Detailing
Handles your harshest chemicals without cracking
The chemical-resistant plastic holds up to the alkaline pre-washes and acidic fallout removers detailers use daily. The ribbed outer profile means you can crack it open mid-wash with wet gloves on, without fighting for grip.

Questions
Frequently asked
Which foam cannon does this cap fit?
This cap is designed specifically for the MJJC Foam Cannon Pro. It is not a universal cap and may not fit other MJJC models or third-party cannons.
Is this a genuine MJJC part or an aftermarket copy?
It is a genuine MJJC replacement part, manufactured to the same specification as the cap that ships with the Foam Cannon Pro.
My cap cracked after using a strong alkaline pre-wash. Will this one hold up better?
The cap is made from chemical-resistant plastic rated for use with detailing chemicals, including alkaline pre-washes and acidic fallout removers. Always rinse the cannon after use to extend the life of all its components.
How do I fit the replacement cap?
Remove the old or damaged cap by turning anti-clockwise. Thread the replacement cap on clockwise and hand-tighten until snug. Do not use tools - over-tightening can damage the threads on the bottle or cannon body.
My cap is not leaking but the grip has worn smooth. Is it worth replacing?
Yes. A worn ribbed surface makes it harder to open the cannon under pressure or with wet gloves. A fresh cap restores that grip and reduces the risk of cross-threading when refilling quickly on a job.
Can I use this cap with any bottle, or only the MJJC bottle?
The cap is threaded to fit the MJJC Foam Cannon Pro bottle. Compatibility with other brand bottles depends on whether the thread pitch and diameter match - we recommend using it only with the intended MJJC bottle to guarantee a leak-free seal.
Should I carry a spare cap in my kit?
For mobile detailers, yes. A lost or cracked cap means the cannon is out of action until a replacement arrives. Keeping one spare in your kit bag costs very little and removes a potential day-stopper.
Does the cap affect foam thickness or lance pressure?
Indirectly, yes. A worn or poorly sealing cap allows pressure to escape from the bottle connection, which reduces the pressure differential that draws solution up into the lance. A properly sealing cap ensures the cannon performs as designed.
