Unger discontinued the HTKI4 HiFlo nLite Hybrid Starter Kit, which puts any crew still running one in an awkward position: the 22 foot pole, the brush and the hose are all perfectly serviceable, but a single cracked coupling can take the whole kit out of service. This is that coupling. The 11MQC is the genuine Unger quick connect socket specified for the HTKI4, and it is usually the cheapest possible way to get a working pure-water setup back on the truck.
Built for
- Window cleaning crews still running an Unger HiFlo nLite hybrid pole kit
- Repairing a quick connect that has cracked, split or stopped holding
- Keeping a spare in the van so a failed fitting is a two-minute fix, not a lost day
- Solar panel and storefront cleaners using nLite poles for daily route work
- Rebuilding a used HTKI4 kit bought secondhand
Why the coupling is the part that fails
On a water-fed pole the quick connect is handled more than anything else in the system. It gets connected and released at every stop, dropped on concrete, pulled sideways when the hose snags, and left in the sun between jobs. The pole sections and the brush generally outlast several couplings. Because the connection is tool-free by design, a socket that has gone loose or cracked will not simply leak a little; it will let go under pressure at the worst possible moment, usually with the pole extended. Carrying a spare socket is standard practice for crews who depend on the equipment daily.
About the HTKI4 kit
Unger built the HTKI4 as a complete starter package for pure-water window cleaning: a four-section HiFlo nLite hybrid master pole reaching roughly 22 feet, an 11 inch rectangular nLite brush, a MultiLink adapter, a 36 foot nLite hose and a pair of spare fan jets. Because the kit is no longer produced, individual spares like this socket are what keep those systems running.

Frequently asked questions
What exactly does this part do?
It is the socket half of a quick connect coupling on the Unger HiFlo nLite system. It lets the connection be made and broken by hand, with no tools, so a pole can be set up and broken down quickly on a route.
Will it work with my nLite pole if I do not have an HTKI4 kit?
This socket is listed for the HTKI4. Unger builds several coupling styles across the HiFlo and nLite ranges, so match the fitting on your own pole before ordering rather than assuming all nLite parts interchange.
Is the HTKI4 kit still available?
No. Unger has discontinued the HTKI4 starter kit. Spare parts like this socket are what allow existing kits to stay in service.
Does it come with the plug half of the coupling?
No. This listing is for the socket only. If the mating half is also damaged, order it separately.
Should I keep a spare on the truck?
Most full-time crews do. The coupling is the most handled part of a water-fed pole system, and a failure on site stops the job until it is replaced.
Discount Cleaning Products stocks Unger window cleaning equipment and spare parts, with US-based order support for crews that need a specific fitting rather than a whole new kit.
