The Plug and Play Hose
system consists of Parflex 515H
hose and the Parker RA (Rapid Assembly) quick connecting hose fittings and
adapters. Parflex 515H hose is a light weight, fiber reinforced, low pressure
thermoplastic hose that has great kink resistance. Typically, a Â¼ inch 515H
hose has a 20 percent smaller diameter than a standard 100R1 hose and a 25
percent tighter bend radius. It is also 5 times lighter than comparable hoses.
The brass RA quick connect fittings offer plug and
play convenience in a very compact, anti-corrosive and economical system. The
connector design is simple, durable and easy to install, eliminating the need
for wrenches or other tools. However, the RA series fittings are not live swivels and care should be
taken to insure that relative movement between the adapter and the hose fitting
is eliminated. Sealing is achieved through the use of petroleum
and synthetic hydraulic oil resistant elastomeric o-rings.
Parflex 515H hose is useful
for routing through tight spaces while maintaining the flexibility of a more
robust hose and is often used in pilot lines or joy stick applications where
multiple hoses are required to fit into a tight space. Sizes range from 3/16
I.D. up to Â½ inch I.D. in a single or multi-line assembly.
Industrial workplaces are governed by OSHA rules, but this isn’t to say that rules are always followed. While injuries happen on production floors for a variety of reasons, of the top 10 OSHA rules that are most often ignored in industrial settings, two directly involve machine design: lockout/tagout procedures (LO/TO) and machine guarding.
