Detailed Description
The 1102 combines pre-formed geometry with braided reinforcement, addressing unbraided hose limitations in pressurized circuits. Unlike straight hoses requiring field bending-which crushes the bore and creates stress-the 1102 is molded to exact 3D shapes in a heated press, with reinforcement braid integrated during forming.
The inside braid layer-polyester for general service, aramid for high strength-elevates working pressure from 0.5 MPa (unbraided) to 1.5 MPa, enabling pump discharge and high-flow main line applications. The pre-formed cover seals the braid from coolant splash, UV, and abrasion while maintaining low-extractable properties.
Materials: IIR (butyl rubber) for lowest gas permeability, CIIR (chlorobutyl) for improved vulcanization compatibility, EPDM for widest temperature and coolant compatibility. This triple-layer architecture-pre-formed tube plus braided reinforcement plus pre-formed cover-delivers routing precision of rigid piping with flexibility and vibration isolation of a hose.
Product Application
Data center liquid cooling is the primary application: the 1102 connects cold plates to CPU/GPU heat sinks in direct-to-chip systems, where pre-formed 90° and 45° elbows eliminate kinks restricting coolant flow. In rack-level manifolds, these hoses distribute chilled glycol from the CDU to server blades, ensuring flow balance across nodes.
For immersion cooling, the 1102 serves as supply/return connections to dielectric fluid heat exchangers, where low extractables prevent contamination. EV battery thermal management: pre-formed hoses route glycol through battery pack cooling channels without sharp bends causing fatigue over 10+ years. EVSE cooling: pre-formed shapes allow compact routing inside the cabinet, preventing thermal throttling of fast-charging modules.

Data Center Liquid Cooling Application Guide
- Cold plate connection: pre-formed 90° elbows mate to cold plate ports, eliminating field-bent hoses that restrict flow. Recommend 1/4" sizes for single-phase systems.
- Manifold routing: Recommend 3/8" – 1/2" sizes, pre-formed tees and offsets distribute flow across 4–8 server slots; specify equal-length legs to balance pressure drop (target ΔP < 0.05 MPa).
- CDU connection: larger diameters (3/4" to 2") for main supply/return lines; pre-formed S-bends absorb thermal expansion without stressing quick-disconnect fittings.
- Installation tip: support pre-formed hoses at both ends with cushioned clamps; never use the hose as a structural member.
FAQ
Q1: What is the difference between the 1101 series and 1102 series?
A1: The 1101 is a basic pre-formed tube without reinforcement (0.5 MPa), for gravity-feed and low-pressure returns. The 1102 adds inside braid and pre-formed cover, raising working pressure to 1.5 MPa for pump discharge and high-flow mains. Choose 1101 for simple routing; 1102 when pressure, vibration, or external protection matter.
Q2: Can you produce custom pre-formed shapes?
A2: Yes. Provide your 3D CAD model (STEP, IGES, or SolidWorks) and we design the mold, produce first-article samples within 15 working days, and deliver production quantities within 20–25 working days after approval. Minimum order: 200 pieces.
