HS-79 Ultra-Lite flexible smooth bore PTFE hose assemblies are truly state-of-the-art.
◆ 4-ply composite construction is at the core of HS-79’s distinctive list of advantages.
HS-79’s smooth-bore design offers:
◆ extremely high flow rates, pressure and temperature ratings (-65˚ to +400˚ F)
◆ lower pressure drop than comparable systems.
In addition, HS-79 provides:
◆ extreme flexibility and ease of installation and cleaning.
◆ Tight bend radius
◆ higher vacuum capacity are possible because HS-79 has a
◆ higher hoop strength.
Moreover, XRP’s HS-79 assemblies feature a noticeably
◆ larger inner diameter.
Look inside the fittings below and compare for yourself.
It is this generous inner diameter that gives HS-79
◆ greater flow capacity and better performance on race day.
◆ greater flow is only part of the story of optimizing fluid delivery!
The characteristics of the flow are critically important to the racer as well.
HS-79’s smooth-bore “non-convoluted” design
◆ eliminates boundary layer entrapment and flow disturbance for race day performance you can count on!
◆ compatible with all racing engine fluids, including gas, alcohol, and nitromethane and
◆ can be assembled with either 37˚ JIC hose ends or aluminum quick disconnect clamshell couplings.
The ideal choice for service situations that are time sensitive, you will find our clamshell couplings shown on pages 24-25 of this catalog.
