Mechanical devices which use the power of compressed gas to produce a force in a reciprocating linear motion.

Duck Bills

Duckbill valves are unique, one-piece, elastomeric components that act as backflow prevention devices or one-way valves or check valves.

Rubber to Metal

These are vulcanization bonded products of rubber and metal or rubber and resin with higher adhesive reliability. 

Air Regulators

Allows high-pressure fluid or air supply lines or tanks to be reduced to safe and/or usable pressures for various applications.

Flow Regulators

Flow Regulators are constant flow regulating valves, which are components that control the flow of water. 

Umbrella Valves

Precise check valves which have shapes that utilize the deformation and sealing properties of rubber materials.


Flexible seals prevent unwanted transmission of substances between two places. Essential in flow control applications.

Rolling Diaphragms

BF Diaphragms are special diaphragms shaped like top hats which provide the properties both of bellows and diaphragms. 

Check/Relief/Needle Valves

Our valves fit for general machinery, medical equipment, analytical instruments, etc. Our new lineup includes high-performance check valves, relief valves, and needle valves with adjustability of micro flow rates.

Custom Products

IER Fujikura is experienced in all types of synthetic elastomers and we pioneered the molding of fluorinated elastomers.


The lineup includes products such as umbrella and check valves made of medical silicone for infusion circuits, and high-performance compact regulators and valves for medical equipment.
