The Intaflex Heat Pump Hose Kit (Straight, pair) is a pre-insulated flexible connection set designed to link an air source heat pump's flow and return ports to the rigid pipework of the primary heating circuit. Each hose runs straight through from the heat pump connection to the pipework, making it well suited to installations where the pipe run continues in line with the unit.
Manufactured by Intatec, the hoses are supplied in a matched pair to cover both the flow and return connections and arrive pre-insulated with 19mm thick Primary Pro insulation, designed to join seamlessly to rigid pipe insulation for continuous, unbroken thermal protection along the full external pipe run.

Key Features
Straight-Through Configuration
Each hose runs straight through from the heat pump connection to the pipework, suited to installations where the pipe continues in line with the unit.
Stainless Steel Braided Hose
The flexible hose body is sleeved within stainless steel braid for mechanical protection and resistance to abrasion and vibration transfer from the heat pump.
Pre-Insulated for Continuity
Fitted with 19mm thick Primary Pro insulation, designed to connect directly to rigid pipe insulation so the whole external run stays covered, preserving system efficiency.
1" Female BSP Swivel
A 1" female BSP swivel connection at the heat pump end allows the hose to be fitted without twisting, simplifying alignment during installation.
28mm Compression Fitting
The pipework end uses a 28mm compression fitting, suitable for direct connection to standard copper pipe on the primary circuit.
MCS Installation Specification
Manufactured to meet MCS installation specification requirements for heat pump ancillary components.

Good to Know: This is the straight version, product code HPHOSE750. A matching 90° elbow version (HPHOSE750B) is also available where the pipe run needs to turn away from the heat pump connection.
Frequently Asked Questions
What is the difference between the straight and elbow versions of this hose?
The straight version (HPHOSE750) runs directly in line from the heat pump connection to the pipework. The elbow version (HPHOSE750B) has a 90° bend built into the pipework end, used where the pipe run turns away from the heat pump.
How many hoses are included in this kit?
The kit is supplied as a pair (2 hoses), covering both the flow and return connections on the heat pump.
What size pipework does this hose connect to?
The pipework end uses a 28mm compression fitting, suitable for standard 28mm copper pipe on the primary heating circuit.
Is the hose suitable for use with glycol-based heat transfer fluid?
Yes, the hose is rated for use with water or a water and glycol mixture, commonly used as an antifreeze measure on external heat pump pipework.
Does the hose insulation match the rest of the pipe run?
Yes, the hose is pre-insulated with 19mm thick Primary Pro insulation specifically so it can be joined directly to rigid pipe insulation, maintaining continuous thermal protection along the pipe run.
