Brand & System Insights
The ARG GJ101 gunite venturi tee is used in spa plumbing loops to blend water from a 1.5" line with air from a 1" line before the flow reaches jet bodies. The long 10" profile is typical of gunite spa venturi tees and is commonly used in Spa Master–style systems. It is dimensionally similar to CMP 23308-000-000 venturi tees, but you should always confirm socket size, air connection, and venturi port style against your existing part before treating it as a direct replacement.
This fitting is designed as a permanent, in-shell component. Once the spa is shot and plastered, access is limited, so matching the original layout and using proper solvent welding is critical for long-term reliability.

FAQs
Q: What size plumbing does the GJ101 venturi tee work with?
A: It is designed for gunite spa systems that use a 1.5" socket connection on the water line and a 1" spigot on the air line, with a standard 7/16" threaded venturi nozzle port. Always confirm pipe size, schedule, and nozzle style against your existing tee before purchase.
Q: Will this replace a CMP 23308-000-000 venturi tee?
A: GJ101 is commonly used where CMP 23308-000-000 style tees were installed, but you should treat it as a dimensional match only after you verify socket depth, spigot length, and venturi port style. If anything differs, stay with the exact OEM spec or consult your builder.

Description
The ARG Gunite Jet 10" Venturi Tee 1" Air (GJ101) is a deep-set spa plumbing body that combines water, air, and a venturi nozzle to feed gunite jet assemblies. The 1.5" socket takes the main water line while the 1" spigot ties into the air loop, creating a strong venturi draw once the pump and blower come online. When installed with clean cuts, proper primer, and fresh cement, this tee helps prevent hidden weeping behind the shell and keeps jet zones balanced. GJ101 is also used as an aftermarket option where CMP 23308-000-000–style venturi tees were originally installed, but you should always confirm line size, venturi port style, and orientation before using it as a replacement.
Pro Tip
Mock up the loop on the ground first. Dry-fit, mark each joint, and confirm jet spacing before you shoot gunite or close walls. After the glue cures, pressure-test the line and verify there is no slow loss before backfilling or plastering.
