IHARA SCIENCE CORPORATION
IHARA VTF Series Metal Gasket Seal Fitting
Product Made In Japan
Manufacturer: IHARA SCIENCE CORPORATION
Model: VTF Series
◆Features
１．Wide range applications from ultra high vacuum to high pressure, lower and higher temperature through metal gasket seal.
２．Spacing when install and uninstall can be minimized.
３．As the nut thread is silver plated and lubricated, tightening torque is reduced and also free from galling.
４．Thrust washer (VSTW) and thrust bearing (VTJR) are available for the protection from co-rotation of the tube when tightening female nut.
５．Material of the parts to be welded is SUS316 and is machined highly accurate.
６．For customers demanding high purity and ultra-high performance fittings, we offer products that come standard with W melt (VIM+VAR) materials, double melt material with almost no non-metallic inclusion and vey low impurities such as Mn.
７．After the precision cleaning, protect seal surface of the fitting and vacuum packed one by one inside clean room.
８．Identification label showing product type, part symbol, inner roughness etc. is put on each product package.

◆Nomenclature
◆Types
To ensure that our customers are satisfied with the applications and cost performance of our products, we also offer the three types beyond our standard combination.
①Thrust bearing inserted type
Smooth tightening keeps tightening torque low for the female nut. Useful for preventing co-rotation with the gland, and minimal twisting during piping work.
②Compact (High flow) type
Very compact, but realized high flow.
Reference: Data of gland co-rotation (in-house test data)
| Size | Standard | Thrust washer/bearing inserted |
|---|---|---|
| Tightened 1/8 turn | Tightened 1/6 turn | |
| 1/4″ | 2° ~ 2°30′ | 0°18′ ~ 0°30′ |
| 1/2″ | 2°30′ ~ 3° | 0°30′ ~ 1° |
Any type of customized products are available, for instance, with less fittings and less welding.
Feel free to inquire your customized requirement.
