Donut wing, stable underwater
The oval air cell forms a continuous loop, so the wing is streamlined and very stable underwater, with no dramatic shift of air from left to right. Apeks shapes it so the cylinder nests deep inside.
WTX-D40 Complete Kit
Wing, backplate and harness, assembled in one kit
The WTX-D40 Complete Kit pairs the WTX-D40 wing with a deluxe harness, fully assembled by Apeks, for seasoned technical divers and anyone looking to take their diving to the next level. Single-cylinder wings, often called donuts, began in technical diving but are becoming very popular with recreational divers. The continuous loop makes the wing streamlined and very stable underwater. Choose an aluminium or a stainless-steel backplate. Designed by Apeks and built in its own factory.

Highlights
Complete and pre-assembled
You get the WTX-D40 wing, a backplate, the deluxe webbed harness with stainless-steel hardware, 2 Griplock tank bands and 2 book screws, fully assembled by Apeks, so there is nothing to buy piece by piece.
Aluminium or stainless-steel plate
Apeks offers the kit with either an aluminium or a stainless-steel backplate; everything else in the kit is the same.
Part of the WTX system
The wing is not permanently attached to the harness, so it mates up with the rest of Apeks' WTX harnesses, plates and accessories and can be configured to match the diving you do.
Who it is for
Great for

- Technical divers on a single cylinder
- Anyone who wants a complete, pre-assembled kit instead of buying parts one by one

FAQ
WTX-D40 or WTX-D30 Complete Kit: what is the difference?
The parts list is the same: a backplate, the deluxe webbed harness with stainless-steel hardware, 2 Griplock tank bands and 2 book screws, fully assembled. The difference is the wing (WTX-D40 or WTX-D30). Still deciding? Ask us on LINE and we will help you choose.
How much lift does the wing give?
Apeks' WTX-D40 kit pages do not state the lift. Ask us on LINE before you order.
Aluminium or stainless-steel plate: what is the difference?
Everything in the kit is the same except the backplate material. Apeks' pages do not list the weight of each, so ask us on LINE and we will help you choose.
I am not a technical diver. Is it for me?
Apeks says single-cylinder wings began in technical diving but are becoming very popular with recreational divers, and it made this kit for seasoned technical divers and anyone looking to take their diving to the next level. Never used a backplate and wing? Ask us on LINE before you order.
Do I need to assemble it?
No. Apeks supplies the kit fully assembled.
