Mosmatic

Mosmatic is the Swiss-built gear pros reach for after a bargain swivel has failed them twice. Sun Brite Supply carries Mosmatic live swivels, 90 degree hose reel swivels, stainless surface cleaners, duct cleaners, and the seal kits that keep all of them spinning.

How to Pick the Right Mosmatic Swivel

Every Mosmatic swivel does one job. It lets the line rotate so your hose stops twisting itself into kinks while you work. Where the swivel lives decides which family you need. Match three things and you are done: location, thread size, and pressure rating.

Live swivels for guns and wands

The DGV series is the workhorse. It installs between the hose and the gun inlet, carries a 4,000 PSI rating, and spins under full pressure so the hose lays flat behind you instead of fighting your wrist. Threads run from 1/4" to 1/2" NPT in male and female combinations. If your rig uses 22mm screw couplers, the DKS live swivel delivers the same relief in a screw-on format. On a long driveway day, a live swivel at the gun saves your forearm more than any other $70 part on the truck.

90 degree swivels for reels and surface cleaners

The WDB and WDE families turn the water 90 degrees while rotating, which is exactly what a hose reel inlet or a surface cleaner tower needs. WDB units use a stainless stem for hot water duty. The WDEI variants go full stainless for chemical exposure on soft wash trailers. For surface cleaner towers, the DY family carries the load. The DYDI triple bearing carbide swivel is rated to 7,300 PSI and is the permanent fix when a budget surface cleaner keeps eating its own swivel.

Rebuild before you replace

Mosmatic sells seal kits for nearly every swivel they make, and that changes the math. A WDE seal kit costs about $17. A carbide seal kit covering all DY swivels runs about $120. Either beats tossing a $170 to $600 swivel because it started weeping at the stem. When a Mosmatic swivel drips, reseal it. The bearings usually have years left in them.

Mosmatic Surface Cleaners: DLK, DLFK, and Turbo Flex

Mosmatic surface cleaners pair polished stainless decks with counterbalanced rotor arms and the same self-lubricating bearing swivels that built the brand's name. Most are rated to 4,000 PSI and 250 F, so hot water rigs do not bother them. The DLK series rides on casters at a fixed height. The DLFK series floats on the water cushion, which holds nozzle height steady over rough or wavy concrete. The Turbo Flex TFK squeezes into tight spots at 11.8 inches. Size the deck to your flow, not your ambition. A 4 GPM machine runs a 19" to 21" deck well. Save the 27" to 39" decks for 5.5 GPM and up. Put a 39" deck on a 4 GPM machine and you will leave stripes, not clean concrete.

From the Field

Two seal kits sit near the top of our Mosmatic sales, and that tells you the real failure story. These swivels do not break. They wear seals, and almost always because grit got in. Unfiltered water sandblasts the seal faces from the inside, and a swivel that starts dripping and keeps running lets that grit ride straight into the bearings. So run a filter ahead of the pump, reseal at the first steady drip, and the swivel outlives the machine. One more counter tip: when a customer burns through three cheap surface cleaner swivels in a season, we stop selling them cheap swivels. One DYDI carbide unit ends the cycle.

Frequently Asked Questions

Why do Mosmatic swivels cost more than import swivels?

Swiss machining, stainless internals, and self-lubricating bearings. The bigger difference is that Mosmatic swivels are rebuildable. A cheap swivel gets thrown away when it leaks. A Mosmatic gets a seal kit and goes back to work.

Which Mosmatic swivel goes on a pressure washer gun?

Use a DGV inline live swivel if your gun and hose use NPT threads. Use the DKS if you run 22mm screw couplers. Both spin under full pressure so the hose stops torquing your wrist.

Can I rebuild a leaking Mosmatic swivel?

Yes. Seal kits run from about $17 for WDE swivels to about $120 for the carbide kit that fits all DY swivels. Reseal at the first steady drip and the bearings keep going.

What pressure and temperature are Mosmatic products rated for?

Most swivels and surface cleaners carry a 4,000 PSI rating, with surface cleaner decks good to 250 F for hot water work. The DYDI triple bearing swivel is rated to 7,300 PSI. Check your exact model number before running high pressure.

What size Mosmatic surface cleaner should I buy?

Match deck width to flow. Around 4 GPM, run a 19" to 21" deck. At 5.5 GPM and up, the 27" to 39" decks make sense. Too much deck on too little flow leaves striping you will have to rewash.

What is the difference between DLK and DLFK surface cleaners?

DLK models ride on casters at a fixed nozzle height. DLFK models float on the water cushion, which keeps the nozzles at a consistent height over rough or uneven concrete. Flatwork crews on old aggregate usually prefer the floating deck.

Do you keep Mosmatic in stock or is it order-in?

Much of the Mosmatic line is order-in with quick turnaround. Call 301-519-9274 with the model number and we will give you a real lead time instead of a guess.
