P4 Series
P4 hose and braid represent a new generation of products manufactured using an innovative production process which allows for longer lengths, uniformity of corrugations and consistency of pitch.
The series promises a bright, clean finish with a high coverage braid that sustains high working pressures and provides maximum protection. Penflex carefully packages long continuous lengths of P4 braided and bare hose on durable reels for shipment by air, truck or ocean. We package loose braid products with the same care into durable carton boxes.

American Iron & Steel (AIS) Compliant Options
For projects with 100% domestic sourcing requirements, Penflex offers AIS compliant versions of P4 and 700 Series hose and braid. While AIS requirements apply specifically to water infrastructure projects, products manufactured to AIS standards may also support broader domestic sourcing initiatives, including Build America, Buy America (BABA) and Defense Federal Acquisition Regulation Supplement (DFARS).
AIS requirements mandate that:
- Stainless steel strip used to form hose is melted and produced in the United States
- Stainless steel wire used for braid is melted and drawn in the United States
- All manufacturing processes take place domestically
