| Dimensional standard | As per the Lata Scientific component datasheet |
Product overview
What it does, and where it fits.
A blind seals a flange face flat, adding almost nothing to the length of the run — 8 mm up to DN 100 and 9 mm from DN 150 upward. That makes it the right choice for blanking a branch or isolating a section where a domed closure would not fit.
Nine bores are covered from DN 15 to DN 300.
Features
Built into every unit.
- Only 8–9 mm thick — negligible addition to run length
- DN 15 to DN 300
- Seals flat against a flange face
- Borosilicate 3.3
Benefits
Why it earns its place in the line.
- Completely inert to almost all process media — no metal pick-up and no contamination of the batch
- Full visibility of the process along the whole line
- Smooth, non-wetting bore that resists fouling and cleans easily
- Excellent thermal shock resistance from borosilicate 3.3
- Modular flanged construction — sections can be swapped without cutting or welding
Applications & industries
Where it is specified.
Typical applications
- Blanking a spare branch on a tee or cross
- Isolating a section for maintenance or hydrotest
- Capping a run where length is tight
- Future tie-in points left blanked during construction
Industries served
- Chemical processing
- Pharmaceutical
- Fine chemicals & dyes
- Food & beverage
- Water & effluent treatment
- Distillation & solvent recovery
- Research & pilot plant

FAQ
Questions we are asked about this item.
8 mm up to DN 100 and 9 mm from DN 150 — effectively nothing. Allow for it plus the gasket when setting out.
Blind where length is tight or you are blanking a branch; closure where you want a domed, fully visible end to the run.
