What Is the BWG Hydro Air Mark II Jet Retainer Ring?
The BWG Hydro Air Mark II Jet Retainer Ring (Part No. 30-5842WHT) is a durable, OEM-quality replacement component designed to secure the jet body in place within your hot tub's hydrotherapy system. Over time, jet retainer rings can crack, warp, or wear down due to chemical exposure and regular use. A faulty retainer ring can lead to reduced water pressure, jet movement, or leaking — all of which affect your spa experience.
Replacing this small but critical component restores full jet function and helps prevent further damage to surrounding parts.

Frequently Asked Questions
How do I know if the BWG Hydro Air Mark II Jet Retainer Ring fits my hot tub?
The best way to confirm fit is to locate your hot tub's make, model, and serial number — usually found on a sticker inside the equipment compartment or on the cabinet exterior. You can also photograph the existing jet assembly and send it to fixmytub@gmail.com. Our team will verify compatibility before you place your order.
What does a jet retainer ring do?
The jet retainer ring locks the jet body into the wall fitting of your spa shell. Without a properly functioning retainer ring, the jet can become loose, spin freely, leak, or lose water pressure. Replacing a worn or broken retainer ring is one of the most cost-effective repairs you can make to restore full jet performance.
Is this an OEM part?
Yes, the 30-5842WHT is a BWG (Balboa Water Group) branded component — one of the most widely used and trusted manufacturers in the hot tub industry. It is designed to meet original equipment specifications for compatible models.
What does the "WHT" suffix mean?
WHT stands for White, referring to the color of the retainer ring. If your existing jet ring is a different color (such as gray, black, or beige), contact us to explore available color options.
