THE HOLID PORTFOLIO
A flagship product inside a broader supply system.
FRPU gets the deepest engineering coverage because it is HOLID’s strongest current tube line. Standard PU, PA6 nylon and the matched fitting system are now published beside it as real product families—not placeholder categories.

PRESENTATION VIEWS + RAW TEST EVIDENCE
Flagship depth without narrowing the whole brand.
The site leads with FRPU because it currently has the clearest verified performance record—not because HOLID supplies only one tube. PU and PA6 are now published where the current range data is consistent; conflicting historic ratings stay out until reconciled.
- Visible double-layer construction
- Real bend and peel checks
- Model-specific pressure and dimensions
- Matching 6 mm and 8 mm connectors
