Diversitech tg-30-1 Leak Test Gauge 0-30 Psi 1 in Fpt

Product Description

The DIVERSITECH tg-30-1 is an analog leak test gauge designed for pressure testing HVAC, refrigeration, and plumbing systems. It reads from 0 to 30 psi and connects via a 1-inch female pipe thread (FPT) fitting, making it compatible with standard test port assemblies on both ducted and ductless systems. Technicians use this gauge to verify system integrity after installation or service, confirming that piping, fittings, and coils hold pressure before charging or putting a system back into operation. The analog dial provides a straightforward, easy-to-read pressure indication without batteries or electronics.

This gauge is suited for residential and light commercial HVAC service, refrigeration line set testing, and plumbing pressure verification. Its 1-inch FPT connection accommodates commonly used test manifolds and adapters found in the field. The 0 to 30 psi range is appropriate for low-pressure leak checks on refrigerant circuits, gas piping pre-charge tests, and water supply line verification where moderate test pressures are specified by code or manufacturer procedure. Compatible with both ducted split systems and ductless mini-split applications.

Key Features

• Analog dial display — no batteries required, reliable in field conditions
• 0 to 30 psi pressure range suited for low-pressure leak testing protocols
• 1-inch FPT connection for compatibility with standard test assemblies and adapters
• Suitable for both ducted and ductless HVAC system applications
• Compact gauge format for use in tight mechanical spaces

Compatibility

Designed for use on both ducted and ductless HVAC and refrigeration systems requiring low-pressure leak verification. The 1-inch FPT connection fits standard field test adapters and manifold assemblies used across residential and light commercial applications.

Installation Notes

This gauge is installed by licensed HVAC technicians or plumbers during pressure testing procedures. Isolate the system section under test and ensure all power and refrigerant supply is off before attaching the gauge. Follow applicable code requirements — such as IFGC for gas piping or manufacturer specifications for refrigerant circuits — when selecting test pressure and hold time. Do not exceed the 30 psi maximum rated pressure of this gauge.
