Parker 919 Hose

Why use Parker 919 Hose?

Parker 919 series hose is constructed with minimum .030″ PTFE tube wall to withstand both harsh chemicals and high temperatures. Industries commonly use this hose because it complies with SAE or FDA standards, although some simply use it because of the durability and longevity the PTFE inner tube provides. Over time, harsh chemicals and oils essentially eat away at the inner tube if the material is not designed to withstand that particular media. Once the inner tube breaks down, the fluid can begin to eat through the metal reinforcement jacket. After enough time goes by, the hose could eat through the cover. Obviously, not good if you’re dealing with potential environmental and health hazards.

Which PTFE hose is right for my application?

There are 4 types of 919 hose, each with their own distinct characteristics. We’ll break them down for you.

919/919B Hose

919/919B Hose
Parker 919 hoseIndustry uses for 919/919B hose include the transfer of chemicals, hydraulic fluids, compressed air & gas, and coolants. 919 and 919B hose are virtually identical with the exception of one major difference. The inner tube for 919 hose is a natural FDA compliant PTFE material while 919B type hose has a black static-dissipative core tube. For this reason, you should use 919B hose when conveying non-conducting media such as oils, paints, fuels, steam, and so on.

Inner tube: 919 – Natural FDA Compliant PTFE | 919B – Black Static-Dissipative PTFE Reinforcement: 304 stainless steel braid

Operating Parameters

  • Temperature Range: -100°F (-73°C) to +450°F (232°C)
  • Change in length at Max. Working Pressure: +2% to -4%
  • Min. Burst Pressure is 4x Max. Working Pressure at 73°F (23°C)

Certifications

  • Meets/Exceeds SAE 100R14A (919)
  • Meets/Exceeds SAE 100R14B (919B)
  • FDA 21 CFR 177.1550 (919 Natural tube)

919J Series Hose

919J hose is the better option if an outer layer of protection is important. It has a silicone cover to protect the stainless steel wire reinforcement from fraying. It also prevents external contaminants from entering the transfer line.

  • Inner tube: 919 – Natural FDA Compliant PTFE
  • Reinforcement: 304 stainless steel braid Cover: Extruded silicone

Operating Parameters

  • Temperature Range: -40°F (-40°C) to +450°F (232°C)
  • Change in length at Max. Working Pressure: +2% to -4%
  • Min. Burst Pressure is 4x Max. Working Pressure at 73°F (23°C)

Certifications

  • Meets/Exceeds SAE 100R14A
  • FDA 21 CFR 177.1550

919U Series Hose

Series hose provides a more durable outer layer of protection against fraying and contaminants than 919J hose. The cover is a non-marring, abrasion resistant polyurethane cover, as opposed to silicone. Due to this characteristic, 919U hose is not suitable for use if temperatures could exceed 275°F.

  • Inner tube: 919 – Natural FDA Compliant PTFE
  • Reinforcement: 304 stainless steel braid Cover: Polyurethane

Operating Parameters

  • Temperature Range: -40°F (-40°C) to +275°F (135°C)
  • Change in length at Max. Working Pressure: +2% to -4%
  • Min. Burst Pressure is 4x Max. Working Pressure at 73°F (23°C)

Certifications

  • Meets/Exceeds SAE 100R14A
  • FDA 21 CFR 177.1550
