Rapid Assembly quick-to-connect hose and fitting system for low-pressure hydraulic and pneumatic systems improves assembly time, connector costs and system weight. It consists of
Parflex 515H hose and Parker RA (Rapid Assembly) quick connecting hose fittings and adapters. Parflex 515H light weight, fiber reinforced, low pressure thermoplastic hose has great kink resistance. Sizes range from 3⁄16 to 1/2 in. ID. in a single or multi-line assembly.
Typically, a 1⁄4-in. 515H hose has a 20% smaller diameter than a standard 100R1 hose and a 25% tighter bend radius. It is also five times lighter than comparable hoses. For a technician who is building multiple units each day, the light weight of 515H hose becomes an assembly advantage. Parflex 515H hose is suited 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.
Coupled with the Parker RA quick connecting fittings, hose assembly time continues to decline. Installation and performance tests at several large OEM’s have exceeded expectations in ease of assembly, routing and durability.
The brass RA quick connect fittings offer Rapid Assembly convenience in a very compact, anti-corrosive and economical system. 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.
