General

Do hose stations come with a hose and nozzle, or are they sold separately?

SuperKlean hose stations, hoses, and nozzles are sold separately, so you can build the exact setup your facility needs.

Are SuperKlean hoses and nozzles FDA compliant or food grade?

SuperKlean products are FDA compliant and meet all FDA requirements for washdown and sanitation processes. They are not food grade certified. Food grade certification is typically required only for equipment that carries a substance meant for human or animal consumption, so washdown nozzles, hoses, and related equipment do not require it.

Are SuperKlean products safe to use with potable water?

No. SuperKlean products are not intended for potable (drinking) water. They are designed for washdown only, not for drinking water or food preparation.

Hose Stations

How can I calculate the output flow rate and steam consumption of my DuraMix 8000 hose station?

Download our Flow Rate and Steam Consumption Calculator or our online Steam & Water Calculator to calculate your hot water flow rate and steam consumption. You can also refer to the Temperature Rise vs. Flow Rate Output Chart on page 3.

What is the thread size of SuperKlean temperature gauges?

The thread size of our temperature gauge is 1/2″ NPT.

What are the GVCP-8 and DURA8-7 made of?

The GVCP-8 and DURA8-7 are both made of molded PTFE.

Fittings

How do SuperKlean LifeSpan Hose Guards work, and do I need them?

The most common place an industrial hose fails is on the inside, near each end. Hot water softens the hose, and the edge of the hose barb can gradually cut into the inner wall. SuperKlean LifeSpan internal hose guards protect this wear point, adding minimal cost while significantly extending hose life. See photos and details on page 32 of our catalog.

What material are the hose guards made of?

The hose guards are made of 304 stainless steel.

What is the gasket size for the SuperKlean 8-GHT-B / 8-GHT-S adapter?

The gasket is 0.975″ OD x 0.465″ ID x 0.120″ thick.

Accessories

How much hose fits on SuperKlean hose racks?

Our hose racks hold up to 100 ft of hose, depending on the hose outer diameter and the size of the coils.

What are the dimensions of the SuperKlean 12-SS hose rack?

The technical drawing for our 12-SS hose rack is available on our documentation page and on the product page.

What is the thread size of SuperKlean hose rack bolts?

The thread size of our hose rack bolts is M12 x 1.75.

What size are the mounting holes on the hose rack?

The hose rack mounting holes are approximately 0.55″ in diameter.

How much hose fits on SuperKlean hose reels?

Our hose reels hold a maximum of 50 ft of 3/4″ ID hose. Technical drawings and dimensions for our industrial hose reels are in the hose reel installation manual and on the product page.

Nozzles

What are the pressure and temperature ratings for SuperKlean nozzles?

The recommended maximum pressure is 150 psi, and the maximum temperature is 200°F.

What is the difference between the Mini and Lite nozzles?

They differ in material, design, and size. See the DuraFlow Mini and Lite Nozzle product pages for full details.

Does SuperKlean offer a low-flow nozzle?

We don’t offer a dedicated low-flow nozzle. However, you can achieve low flow on most SuperKlean nozzles by adding a Flow Restrictor Adapter.

What is the O-ring size of the 7-B / 7-S nozzle cartridge?

The O-ring is 18 x 2 mm: an 18 mm inner diameter with a 2 mm cross-section.

Is there lead in the SuperKlean 150A aluminum nozzle?

Yes, our aluminum nozzle contains small traces of lead. For a lead-free option, choose our stainless steel nozzles.

What material are the internal gaskets in DH nozzles made of?

The tip gasket and the cartridge O-ring are both made of nitrile.

Why is the DH150S trigger firmer to squeeze than some competitors’ nozzles?

The DH150S has a more compact design with a shorter lever, and its trigger tension ensures the automatic shut-off works reliably every time. This design also lets you lock the spray pattern with one hand, while some competitors’ nozzles require two.

What is the thread size of the SuperKlean D-Wand tip?

The D-Wand tip attaches to the connector with an M15 x 1.5 thread. The connector attaches to the barrel with an M12 x 1 thread.

Chemical Compatibility

Can SuperKlean nozzles be used with chemicals?

Yes, with the right nozzle. We designed the DuraFlow X Nozzle (DH150X) specifically for washdown with mild chemical solutions. It has been tested against more than 1,600 chemicals, so you can apply cleaners and sanitizers without sacrificing nozzle life. For dairy teat dip applications, choose the DuraFlow D Dairy Nozzle. Our other nozzles are designed for water only, since chemicals can wear their internal seals over time.

Which chemicals are compatible with the DuraFlow X Nozzle?

Common washdown cleaners and sanitizers, including sodium hypochlorite (bleach), peracetic acid, hydrogen peroxide, and citric acid, earn our top Superior resistance rating. See every tested chemical in our Chemical Resistance Guide. Results depend on concentration, so always follow the chemical manufacturer’s dilution guidelines. Don’t see your chemical? Send us its Safety Data Sheet (SDS) and we’ll help confirm compatibility.

How should I care for the DuraFlow X Nozzle after using chemicals?

After each chemical application, flush the nozzle with clean water for about 30 seconds to clear residue from internal parts. This simple habit protects the seals and keeps the nozzle working smoothly for the long haul.
