Tubo in silicone standard

Standard Silicone Hose — Specifications & Standard

1. Product Specifications

Replace the above values with actual test data when preparing a product-specific spec sheet.

2. Applicable Standards

2.1 Automobile / Industrial General

SAEJ20 — the core industry standard for silicone coolant and heater hose.

• SAE J20 R1 Class A: Silicone radiator and coolant hose; covers performance and physical property requirements. Hoses meeting this standard typically also satisfy TMC RP303B and MILSPEC A-A-52426.

• MILSPEC A-A-52426: Military specification, spesso citato insieme a SAE J20 per i tubi in silicone per veicoli pesanti e militari.

• GB/T 18948-2025 (Standard nazionale cinese): Tubi in gomma e tubi in gomma pura per sistemi di raffreddamento automobilistici - specifiche, adozione modificata dell'ISO 4081:2016. Applicabile ai circuiti di raffreddamento di motori a combustione interna o veicoli elettrici con peso lordo inferiore 3.5 T.

2.2 Contatto con il cibo (ove applicabile)

FDA 21 CFR 177.2600 — “Articoli in gomma destinati ad un uso ripetuto.” Questo regolamento elenca i tipi di elastomeri siliconici accettabili per l'uso a contatto con gli alimenti, compreso il metile, metile+vinile, and methyl+phenyl silicone rubbers. MVQ (methyl vinyl silicone rubber) falls within the scope of this section.

Compliance with 21 CFR 177.2600 requires passing the relevant extraction tests (PER ESEMPIO., chloroform-soluble extractives limits). Material type alone does not constitute a compliance claim.

2.3 Aerospace / Specialty (ove applicabile)

• SAE AS4468G: 125 psi lined silicone hose assemblies for aircraft potable water systems, with an all-fluoropolymer liner.

• SAE AS5420G: Heated lined silicone hose assemblies for aircraft potable water systems.

These standards apply only when the product holds the corresponding qualification; they are not applicable to general-purpose industrial Standard Silicone Hose.

4. Note on Data Gaps

Detailed SAE J20 performance values (burst pressure, tensile strength, compression set, eccetera.) are not fully reproduced in publicly available summaries. For a complete spec table, consult the SAE J20 standard text directly or request a conformity test report from the supplier. The framework above is suitable for standard citation and product-page structure, but specific test figures should not be fabricated.
