IPEX 189681 Kwikon PVC Threaded Male Connector with Locknut, Grey
The IPEX 189681 Kwikon PVC Threaded Male Connector is a 1 1/2\" grey PVC fitting engineered to create fast, concrete-tight connections between ENT (Electrical Nonmetallic Tubing) and slab boxes with knockout hubs. Built from durable PVC and supplied complete with a locknut, this connector features a threaded end for secure engagement into knockout hubs and is backed by UL 1653 and CSA C22.2 No. 227.1 certification, making it a dependable choice for concrete slab and underground electrical rough-in work.
Key Features

IPEX 189681 – Frequently Asked Questions
1) What is the IPEX 189681 Kwikon connector used for?
It's a grey PVC male connector that ties Kwikon ENT (electrical nonmetallic tubing) into slab boxes and junction boxes with knockout hubs. The threaded end passes through the knockout and the supplied locknut draws it tight from the inside, so you get a concrete-tight termination for slab and underground rough-in.
2) Will this PVC connector hold up to a concrete pour without pulling loose?
That's what it's built for. The body uses a six locking tab design that grips the tubing and resists pull-out and shifting while concrete is placed, and the grey PVC won't corrode once it's encased or buried.
3) Is the IPEX Kwikon male connector UL listed for electrical work?
Yes. The Kwikon 189681 is UL 1653 Listed and certified to CSA C22.2 No. 227.1, which is the ENT fittings standard on both sides of the border. That matters for inspected slab and underground work in the US and Canada.
4) Can I use this connector with liquidtight flexible conduit instead of ENT?
No. The 189681 is part of the Kwikon PVC ENT system and terminates electrical nonmetallic tubing, not liquidtight flex. For liquidtight you want a dedicated liquidtight connector, such as the Hubbell Wiring PS0509N SwivelLok nylon multi-position connector or the Ocal ST34-G PVC-coated steel straight connector.
5) Can a liquidtight connector like the Hubbell SwivelLok PS0509N be used in place of the IPEX 189681 Kwikon connector?
No. The IPEX 189681 is a PVC threaded male connector with locknut made to join Kwikon ENT to slab boxes with knockout hubs, and it is UL 1653 listed - the standard covering nonmetallic tubing systems. The Hubbell PS0509N is a SwivelLok multi-position liquidtight nylon connector sized 1/2-inch, built to terminate liquidtight flexible conduit, not ENT. The two take different raceways, so one does not drop into the other's opening.
6) Does the Kwikon 189681 connector come with a locknut or do I have to order one separately?
The locknut is included. Each 189681 ships with a matching locknut, so nothing else is needed to land it in a knockout hub.
7) I need a corrosion-resistant connector but the run is steel conduit, not ENT. What should I use?
A PVC ENT fitting like the Kwikon 189681 won't terminate steel conduit. For corrosive or wash-down areas on a steel system, the PVC-coated steel Ocal connectors are the parallel option, ST34-G in 3/4-inch or ST145-G for PVC-coated liquidtight flex.
8) For a corrosive or washdown area where PVC-coated steel is specified, what connector is used instead of the IPEX 189681?
The Ocal ST145-G is a PVC-coated liquidtight flexible conduit connector, and the Ocal ST34-G is a PVC-coated steel non-grounding liquidtight straight connector in 3/4-inch. Both are PVC-coated steel bodies for liquidtight flexible conduit, where the IPEX 189681 is an all-PVC threaded male connector with locknut intended for Kwikon ENT running into slab box knockout hubs.
9) What connector should I use if the conduit enters the box at an angle?
The IPEX 189681 is a straight threaded male connector with locknut, so the ENT must approach the knockout hub in line with the fitting. Where the raceway comes in off-axis, the Hubbell PS0509N SwivelLok is a multi-position liquidtight nylon connector in 1/2-inch that allows the entry angle to be set - though it lands liquidtight flexible conduit, not ENT.
10) Will the grey Kwikon connector match the rest of my ENT system?
It will. The 189681 is molded in grey, the same colour used across standard Kwikon ENT components, so terminations look consistent with the tubing and couplings on the job.
11) Where is the IPEX 189681 connector made?
Canada. For agencies and institutional buyers tracking sourcing, IPEX lists the 189681 as NAFTA qualifying with Canada as the country of origin.
12) What is the manufacturer part number for the IPEX Kwikon grey threaded male connector?
Order it as IPEX 189681. It's the grey PVC threaded male connector with locknut in the Kwikon ENT fitting line.
13) Is a nylon liquidtight connector equivalent to the grey PVC Kwikon connector for a concrete pour?
They are different products. The IPEX 189681 is molded grey PVC with a six locking tab design for a concrete-tight connection that resists pull-out during pours, and ships with its locknut. The Hubbell PS0509N is a nylon liquidtight connector in the SwivelLok series built for flexible conduit terminations. Match the fitting to the raceway and the embedment requirement rather than to the plastic alone.
