I. Crimping methods:

1. Outer rubber layer is stripped off: A section of outer rubber layer should be stripped off in certain length. It is compatible with standard wire-braid and spiral wire reinforced hoses that meet requirements in GB/T 3683-92, GB/T 10544-03, DIN20022 and SAE100R1A/R2A.

2. Outer rubber layer is not stripped off: It is simple to produce and is compatible with fabric-braid hose and wire-braid hoses that meet requirements in SAE100RIAT/R2AT.

3. Both inner and outer rubber layers are stripped off: A section of inner rubber layer and outer rubber layer should be stripped off in certain length. It is also known as inner locking safe crimping type hose connector, and is compatible with diameter hoses that meet requirements in GB/T10544-89 and UHP wire-braid hoses that meet requirements in SAER12 and DIN20023-4SH.

II. By connection methods to hoses, it includes:

1. Full crimping HP hose connector 2. Removable connectors 3. Vulcanized connector and low-pressure fittings.

By connection methods to pipelines, it includes: hose assemblies if various types: A, B, C, D, E, F, K, M, Q, WA, WB, WC, HD and HC, with no limitations on hose length (from several centimeters to hundreds meters).
