Kraloy FA35 3-1/2" PVC Female Adapter
The Kraloy FA35 is a 3-1/2" PVC Female Adapter designed to create a secure, non-metallic transition between PVC conduit and threaded fittings, enclosures, or equipment. Molded from rigid PVC, this female adapter resists corrosion, moisture, and many common chemicals, making it a reliable choice for conduit systems that demand long-term durability. One end of the fitting is sized for a slip-fit, solvent-weld connection to standard PVC conduit, while the opposite end features female pipe threads that accept male-threaded conduit fittings, hubs, or enclosures. Kraloy engineers its PVC adapters, including the FA35, to help electricians complete clean, code-compliant conduit transitions on commercial, industrial, and residential projects.
Key Features
- Trade Size: 3-1/2" for use with matching PVC conduit runs.
- Durable Construction: Molded PVC material resists corrosion, moisture, and chemical exposure common in conduit installations.
- Female Adapter Design: Slip-fit end bonds to PVC conduit while the female threaded end accepts male-threaded fittings, hubs, or equipment.
- Model FA35: Part of Kraloy's FA series of PVC female adapters built for straightforward, reliable conduit transitions.
- Non-Conductive Material: PVC's non-conductive, corrosion-resistant composition suits it for exposure to moisture and typical jobsite conditions.
- Lightweight Fitting: PVC construction keeps the adapter lightweight for easier handling and faster installation compared to metallic fittings.
- Solvent-Weld Compatible: Slip end is designed for solvent cement bonding to PVC conduit for a secure, permanent joint.
- Threaded Connection Point: Female threads allow direct connection to male-threaded conduit bodies, boxes, or equipment without additional adapters.

Kraloy 078074 – Frequently Asked Questions
1) What trade sizes does the Kraloy FA PVC female adapter come in?
Three trade sizes: 1-1/2 inch (part 078074), 3 inch (part 078077) and 3-1/2 inch (part 078078). Match the trade size to the PVC conduit run, since the slip socket only accepts conduit of its own size.
2) Is there an equivalent to the Kraloy FA series PVC female adapter from another manufacturer?
Yes. The Cantex 51400 series PVC female adapter is the closest cross-brand counterpart: it is the same class of threaded PVC conduit fitting, joining a solvent-weld socket end to female pipe threads. The Kraloy FA adapters are offered in 1-1/2 inch, 3 inch, and 3-1/2 inch trade sizes, so match the Cantex 51400 part to the same trade size as the conduit run before substituting. Both are rigid PVC, so the same solvent cement and the same corrosion resistance apply.
3) Do I need solvent cement to install a PVC female adapter, or does it push on dry?
The slip end is built for solvent cement bonding, not a dry push fit. Prime and cement it to the conduit for a permanent joint. Only the threaded end is mechanical, and that side takes a male thread with your usual sealant or tape practice.
4) Can I use a PVC female adapter instead of a metal fitting in a damp or corrosive area?
That is the usual reason to pick it. The body is molded rigid PVC, which is non-conductive and resists corrosion, moisture and many common chemicals, so it holds up where a steel fitting would rust. It is also lighter to handle than a metallic fitting on larger trade sizes.
5) What is the difference between a PVC female adapter and a male terminal adapter?
A female adapter gives you female pipe threads on the outboard end, so it receives a male-threaded fitting, hub or equipment nipple. A male terminal adapter is the opposite: it presents male threads to screw into a female hub on a box or enclosure. Pick based on what the enclosure or fitting you are landing on already has. Both glue to the conduit the same way.
6) Will a Kraloy female adapter mate with another manufacturer's PVC conduit and fittings?
Threads and socket dimensions follow standard trade sizing, so a Kraloy FA adapter joins standard PVC conduit and standard male pipe threads regardless of who made them. If you would rather stay with one brand throughout, ZenSupply also carries the Cantex 51400 Series PVC female adapter as an equivalent threaded transition fitting.
7) What should I use instead of a PVC female adapter if I need to land conduit into a knockout rather than a threaded hub?
A female adapter is the wrong fitting for that. The Kraloy FA takes a slip solvent-weld conduit end on one side and female pipe threads on the other, so it mates to a male-threaded hub, conduit body, or piece of equipment. For an unthreaded knockout you want a male terminal adapter with a locknut, which threads through the knockout from outside. The Cantex 51400 series female adapter has the same limitation, since it is also a female threaded fitting.
8) Can I mix a Cantex female adapter into a conduit run that is otherwise Kraloy fittings?
Yes, within reason. Both the Kraloy FA and the Cantex 51400 series female adapters are rigid PVC fittings sized to standard conduit trade sizes, so a Cantex 51400 adapter will solvent-weld to the same PVC conduit a Kraloy FA does and its female threads accept the same male-threaded hubs. Kraloy does note that consistent sizing across its own conduit, couplings, and fittings helps its adapters seat cleanly alongside other Kraloy parts, so on a long run with tight socket tolerances it is simpler to stay with one brand.
9) I'm standardizing conduit fittings across a building. Is one brand of PVC female adapter interchangeable with another on the same run?
Functionally yes, for a threaded PVC transition. The Kraloy FA adapters and the Cantex 51400 Series both do the same job: solvent-weld socket to conduit, female thread to equipment. Keeping one brand across a job mainly buys you consistent socket depth and fitting profile, which makes layout and cement work more predictable than mixing lines.
10) Where is a PVC female adapter typically used on an electrical job?
It is the transition point wherever a glued PVC conduit run has to land on something threaded: a threaded hub, a conduit body, a box, or a piece of equipment. Common on commercial and industrial raceway systems, residential wiring, and both new construction and renovation work where part of the system is PVC and part is threaded.
