IPEX 08905 Kwikon PVC Threaded Stub-Down Fitting
The IPEX 08905 Kwikon PVC Threaded Stub-Down Fitting is engineered for direct connection to Electrical Nonmetallic Tubing (ENT) on the horizontal run, with a flanged base that provides an NPSC threaded hub connection on the vertical exit point of the slab. Available across the Kwikon stub-down family in sizes from 3/4" through 1", this design allows a clean, non-metallic transition from ENT to other raceway products without penetrating the form. Built from durable gray PVC, every size in this family delivers a consistent bend radius of 2-1/2" while standing less than 3-3/8" tall, offering the optimal balance of bend radius and overall in-slab height for concrete encasement applications. The fitting features a threaded connection type suited for NAIL or SCREW mounting on the base, making it a practical solution for electricians working on slab-on-grade and underground raceway installations.
Key Features
- Size Range: Offered in 3/4" and 1" trade sizes to match ENT-to-threaded raceway transitions across a range of slab applications.
- Durable Construction: Molded from rugged, lightweight PVC for a concrete-tight, corrosion-resistant design that withstands the rigors of slab installation.
- Threaded Connection: NPSC threaded hub on the vertical base allows direct transition from Kwikon ENT to other threaded raceway products.
- Non-Metallic System: Complete non-metallic system designed for Kwikon x Threaded stub down applications, eliminating the need for metallic raceway components at the transition point.
- Optimized Geometry: Provides a bend radius of 2-1/2" while standing less than 3-3/8" tall across the size range, balancing conductor protection with minimal in-slab height requirements.
- Simple Installation: Streamlined design reduces labor costs and installation time on the jobsite.
- Protective Seal: Integrated protective seal on the base helps keep concrete and debris out of the fitting during the pour.
- Connection Type: NAIL or SCREW mounting connection secures the fitting firmly in place prior to concrete placement.
- Finish: Gray PVC color for easy identification within non-metallic conduit and ENT systems.

IPEX 089059 – Frequently Asked Questions
1) What does the IPEX Kwikon 08905 stub-down fitting connect to on each end?
The Kwikon 08905 takes ENT (electrical nonmetallic tubing) on the horizontal run and gives you an NPSC threaded hub on the vertical exit out of the slab. So the buried side stays non-metallic Kwikon ENT, and the riser side threads into whatever threaded raceway you are continuing with above the pour. No metallic fitting is needed at the transition.
2) Will this stub-down fit in a thin slab?
It stands less than 3-3/8 inches tall while holding a 2-1/2 inch bend radius, which is why it is used where in-slab height is tight. Measure from the top of your deck or form to the finished pour to confirm you have that 3-3/8 inches of cover plus whatever your spec requires over the fitting.
3) How is the Kwikon stub-down held in place before the concrete pour?
The base is flanged for NAIL or SCREW fastening, so you fix it down to the form or deck before the pour and it will not shift when the concrete goes in. There is also an integrated protective seal on the base that keeps concrete and debris out of the threaded hub during placement.
4) Do I need a separate adapter to go from ENT to rigid threaded conduit in a slab?
Not with this fitting. The Kwikon 08905 is the adapter, ENT socket on one leg and a threaded NPSC hub on the other, in one PVC body. If both ends of your run are ENT you do not want a threaded stub-down at all, you want a plain Kwikon ENT stub-down instead.
5) Is this fitting corrosion resistant enough for direct concrete encasement and underground work?
It is molded gray PVC throughout, non-metallic and corrosion resistant, which is the reason contractors use it for concrete-encased and underground-to-above-slab transitions rather than a steel elbow that can rust at the slab line.
6) Is the IPEX Kwikon stub-down sold individually or in a box quantity?
It is sold as a single fitting, one per unit. Order the count you need per stub location, size by size, since the 3/4 inch and 1 inch are separate part numbers (089059 and 089058).
7) Where is the IPEX 08905 Kwikon fitting made, and does it qualify under NAFTA for our procurement paperwork?
Manufactured in Canada and flagged NAFTA qualifying, which is what institutional and government buyers need for trade-agreement documentation on electrical material.
