PU Tube Polyurethane Air Pipe (Forbest) -100 Meter

About Forbest Manufacturing Co., Ltd.

• Established in 1995, the company specializes in a range of insulation and tubing products—including PU tubing—among other materials like silicone, Teflon (PTFE), FEP, PVC.

• They serve industries such as medical, electronics, automotive, 3D printing, and household appliances.

• Key certifications and quality assurances include ISO 13485 (medical-grade quality), FDA, RoHS, and REACH, indicating strong compliance with international standards

• The company emphasizes custom manufacturing (OEM/ODM), quick delivery, and complete sample services.

So while Forbest does list PU tubing among its product categories, I wasn’t able to locate a detailed technical datasheet or specific product model for a PU air pipe offered by them through publicly available sources.

General Specs for Typical Polyurethane (PU) Air Tubing

I gathered some typical specifications from other manufacturers’ offerings for PU pneumatic tubing to give you a baseline. Note that these are not Forbest-specific but reflect industry norms:
