ARG Hydro Gunite components follow common Hydro-style gunite spa jet layouts, where a buried jet body and plumbing loop feed interchangeable nozzles at each seat. The GJ414 4" nozzle insert is designed for those systems when the length and engagement style match your existing parts, but exact dimensions and orifice details are not published and should be treated as N/A.

Because the nozzle sits inside a buried jet body, correct matching is critical. Always compare this insert to a known-good nozzle from the same spa before you rely on it as a replacement.

Warranty terms for this specific nozzle are not listed by the brand (N/A). Coverage typically follows ePoolSupply’s store policy and any installer guarantee on the job. Keep your invoice and any service notes with your records.

Pair this nozzle insert with compatible ARG gunite fittings and eyeball returns when rebuilding or tuning a spa jet loop:

Q: What does the “4" nozzle” spec refer to on this part?
A: It refers to the manufacturer’s nozzle size designation for this Hydro-style insert. Exact orifice and length measurements are not published; match this nozzle visually and dimensionally to your existing insert before purchase.

Q: Will this fit any Hydro gunite jet body?
A: No. It only works when the body style, nozzle length, and locking method match your existing system. Remove an old nozzle, compare side by side, and only use this insert if the fit is effectively identical.

ARG Hydro Gunite Jet 4" Nozzle Insert | GJ414

4" Hydro gunite spa jet nozzle insert for ARG-style jet bodies. Restore a tighter, more focused stream; match to your existing nozzle before purchase. SKU GJ414.

Features

  • Replacement 4" nozzle insert for Hydro-style gunite spa jet bodies
  • Helps recover a strong, focused massage stream from weak or worn jets
  • Installs into compatible Hydro gunite housings when length and style match
  • Lets you refresh jet performance without breaking into the shell or plumbing
  • Suited for continuous immersion in typical pool and spa water conditions

Description

The GJ414 Hydro Gunite Jet 4" Nozzle Insert is a small, service-friendly part that makes a big difference in how your spa feels. When the internal nozzle wears out or scales over, jets lose pressure and start to spray instead of pushing a clean stream. By matching and replacing the insert, you restore the restriction and direction the jet body was designed for, without touching the gunite or main plumbing. This nozzle is intended for Hydro-style gunite jet systems that use a 4" class insert; because detailed dimensions are not published, always compare it to your existing nozzle for overall length, tip profile, and how it locks into the body before you commit it behind finished surfaces.

Pro Tip

When you pull old nozzles, take a minute to inspect the jet body and wall fitting. If you see cracks, heavy chemical damage, or loose fittings, fix those issues first, then install new nozzles so the whole assembly starts fresh.
