FLEXTECH

FLEXTECH is a brand specializing in silicone-based hose products for industrial, automotive, and heavy-equipment applications. The product line includes charge air cooler hoses, heater hoses, vacuum hoses, and pre-formed elbows, all constructed from silicone materials rated for a temperature range of -65° to 350°F (or up to 450°F for charge air cooler hoses). These hoses are designed to handle high-heat environments common in engine bays, turbocharged systems, and industrial heating circuits. FLEXTECH hoses are available in multiple configurations: straight lengths, 45° elbows, and custom diameters from 3/16 inch to 4 inches, with lengths ranging from 6 inches to 25 feet. The silicone construction provides resistance to ozone, weathering, and thermal degradation, making them suitable for continuous-duty applications. Color options include red and blue, which can aid in visual identification of different circuits. FLEXTECH products comply with SAE J20 and SAE J20R3 standards for heater and coolant hoses, ensuring dimensional consistency and pressure ratings appropriate for low-pressure fluid transfer. The vacuum hoses meet general automotive vacuum system requirements. 3G Electric stocks over 75 SKUs of FLEXTECH hoses, providing datasheets with detailed specifications such as inside diameter, length, material composition, and temperature limits. This inventory supports maintenance, repair, and operations (MRO) needs for plant engineers and procurement specialists who require reliable, high-temperature hose solutions for burner systems, pump connections, gas control lines, and engine cooling circuits. The availability of multiple sizes and configurations allows for direct replacement or custom routing without the need for adapters. 3G Electric offers logistics support for global shipping, ensuring that FLEXTECH hoses reach facilities worldwide with minimal lead time.

Frequently asked questions

Common questions about FLEXTECH from 3G Electric.

What temperature range do FLEXTECH silicone heater hoses handle?

FLEXTECH silicone heater hoses, such as those meeting SAE J20R3 standards, are rated for a continuous temperature range of -65°F to 350°F. This makes them suitable for engine coolant systems, industrial heating loops, and other applications where thermal stability is required. The silicone material maintains flexibility at low temperatures and resists hardening or cracking at high temperatures.

Are FLEXTECH charge air cooler hoses suitable for turbocharged diesel engines?

Yes, FLEXTECH charge air cooler hoses, like the CAC40-400 X 6 model, are designed for turbocharged and supercharged air intake systems. They handle temperatures up to 450°F and are constructed from red silicone, which provides resistance to oil mist and thermal cycling. These hoses are typically used between the turbocharger outlet and the charge air cooler inlet.

What SAE standards do FLEXTECH heater hoses comply with?

FLEXTECH heater hoses, including straight and 45° elbow configurations, comply with SAE J20 and SAE J20R3 standards. SAE J20 covers general coolant hose requirements, while J20R3 specifies performance for silicone heater hoses. Compliance ensures consistent wall thickness, burst pressure, and resistance to coolant additives.

Can FLEXTECH vacuum hoses be used for fuel vapor recovery systems?

FLEXTECH vacuum hoses, such as the V-018 model, are designed for general automotive vacuum systems, including those for brake boosters, emission controls, and vacuum actuators. They are rated for -65°F to 350°F and are made from silicone, which resists fuel vapor permeation. However, for direct fuel contact, a fuel-rated hose should be selected.

What sizes are available for FLEXTECH 45° elbow heater hoses?

FLEXTECH offers 45° elbow heater hoses in inside diameters ranging from 1 1/4 inch to 3 1/2 inches, with lengths typically 10 or 20 inches. Examples include 1 1/4 in x 20 in (MPN 45-125 X 10) and 3 1/2 in x 20 in (MPN 45-350 X 10). These elbows are used for routing coolant lines around obstacles in tight engine compartments.
