COUPLINGS
INFORMATION
RYCO Hydraulics manufacture hose couplings in many different styles and sizes to match each RYCO hose series, with a wide range of thread and connection types.
Hose Couplings must be carefully matched to the hose. When the hose for an application has been selected, it is crucial that the couplings to be fitted are designed specifically for that hose. This information is listed in this RYCO PRODUCT TECHNICAL MANUAL on the pages for each Hose Series, and also on the pages for each Coupling Series.
HOSE COUPLINGS CAN BE BROADLY DIVIDED INTO TWO TYPES:
1) FIELD ATTACHABLE COUPLINGS
Attached to the hose using commonly available hand tools. Push-On Hose Couplings and Suction and Return Hose Couplings are often classed as Field Attachable couplings.
2) CRIMP, OR SWAGE, COUPLINGS
Permanently attached to the hose using a crimping, or swaging, machine.
DO NOT MIX / MATCH HOSE AND COUPLINGS FROM DIFFERENT MANUFACTURERS.
It is critical that the hose and coupling manufacturer are the same and that they are assembled using the manufacturer's recommended equipment, components and procedures.
Female Swivel Nut fittings are typically illustrated as “Crimp Nut”, except T7020H.
Generally, RYCO Fittings are as follows:
1. BSPP, NPSM, JIC, JIS, ORFS and SAE nuts are “Crimp Nut” up to and including 1” Hose Size; and “Wire Nut” 1.1/4” to 2” Hose Size.
2. PW and SAE Inverted Flare Male nuts are always “Slip Nut.”
3. JSEALTM, Metric DKL, DKOL, DKS and DKOS nuts are generally “Slip Nut” where possible and “Wire/Crimp Nut” on jump sizes.
4. T7022 is “Wire Nut”.
There are many exceptions to these general rules; for precise information, contact RYCO.
