Testo Filling Hose Set for Pressure Measuring Instruments, 3-Piece, 1.5 m, 1/4 inch SAE, Red/Blue/Yellow (0554 2111)

Refrigeration and air conditioning service requires reliable connections between manifold gauges and system ports. Leaks or bursts in filling hoses can release refrigerant, causing environmental harm and inaccurate readings. This Testo filling hose set provides three colour-coded hoses that connect digital manifolds to refrigeration systems, ensuring a secure and leak-free path for pressure measurement and refrigerant handling.

Who is it for

HVAC technicians and refrigeration engineers who use Testo digital manifolds such as the Testo 550, 557, 550i, 557s, or 570s. The set suits professionals who need durable, high-pressure hoses for daily service work on air conditioning and refrigeration systems.

Main features

• Three hoses in red, blue, and yellow for easy identification of high, low, and service lines.
• 1.5 m length provides flexibility when working around equipment.
• 1/4" SAE connections on both ends for standard manifold and system ports.
