The SPIR STAR 8/2KF high-pressure hose is a base hose for heated hose systems used in automotive hot-melt dispensing. It has a 7.8 mm PTFE bore, two layers of high-tensile steel wire reinforcement, and an outer braid of galvanized steel wire.

For a new dispensing line or a replacement assembly, start with the adhesive temperature, required pressure, and connections at both ends. These details help determine the hose assembly rating, fitting selection, and installation layout.

Set the Working Pressure at Your Process Temperature

SPIR STAR lists a 475 bar (6,888 psi) hose working pressure from +20°C to +50°C. At higher temperatures, use the manufacturer’s correction factors to calculate the hose rating.

For example, at +200°C, the factor of 0.83 gives a calculated hose working pressure of 394.25 bar. The datasheet also gives factors of 0.95 at +100°C and 0.90 at +150°C. The fittings may further reduce the permitted pressure of the finished assembly, so confirm its rating at the intended process temperature.

Match the Connections at Both Ends

The manufacturer lists a G3/8 female swivel insert with a 24°/60° connection. Use the catalogue references below when comparing an existing assembly or preparing a bill of materials.

Component Catalogue reference
Steel female swivel insert T01.08.10.00
G3/8 steel swivel nut T08.08.09.00
Steel sleeve 10830101KF

Provide a drawing or fitting reference for both ends. If adhesive flow is critical, include the grade, process temperature, required flow, and finished hose length. Use the 7.8 mm hose bore and 5.9 mm insert bore as separate dimensions in the specification.

Check Clearance at the Dispensing Head

The base hose has a 13.3 mm outside diameter. For the finished heated line, check clearance around fittings, heating elements, insulation, and any protective jacket.

If the dispensing head moves, review the hose path over its full travel. For dynamic loads, SPIR STAR specifies at least twice the listed bend radius. For the 8/2KF, that gives a starting radius of 170 mm, subject to the actual installation conditions. For conventional hose assemblies, specify suitable corrosion protection for the exposed wire.

Request an 8/2KF Hose Quotation

For OEM builds and maintenance orders, reference Hose Type 8/2KF and datasheet 82KF9. Send the finished length, end connections, adhesive grade, operating temperature, required pressure, and quantity. Include a routing drawing if the hose moves with the equipment or passes through a tight opening.
