[Features]-PTFE can resist most chemicals, usually high temperature resistance, and has a low friction, non-stick surface, excellent electrical insulation properties, non-flammable, low water absorption..
[Function]-Used for chromatographic column packing and mixing beads, PTFE balls can reduce the bumps when corrosive reagents boil..
[Advantages]-Compared with other fluoropolymers (such as FEP and ETFE), PTFE can usually withstand higher temperatures..
[Temperature Resistance]-PTFE is inert to most liquids and vapors, and can be used from -100 degrees Fahrenheit to 545 degrees Fahrenheit..
[Wide Application]-PTFE balls are widely used in chemical, machinery, electronics, ball valves, electrical appliances, aerospace and other fields..

【High Quality】This hose features an PTFE inner layer which is compatible with E85, wrapped by a single layer of stainless steel and nylon. These lines do not deteriorate or swell over time due to E85 use like non-PTFE fuel line. PTFE fuel line holds up a lot stronger to heat and extreme circumstances than the nylon braided fuel line..
【Application】The fuel line is widely used in fuel system, transmission system and cooler system and can be compatible with petrol, diesel, oil, hydraulic fluid, pump gas, alcohol, E85, coolant, fuel, and etc..
【Package Includes】The 6an nylon and stainless steel braided PTFE fuel line kit includes: 6pcs 6an PTFE hose ends (2pcs straight, 2pcs 45 degree, 2pcs 90 degree) and 3/8 PTFE braided fuel line (Length:10ft/3M)..
【Work Condition】The 6an PTFE hose working temperature range: -76℉ to 446℉ (-60℃ to 230℃). It is compatible with nearly every substance or agent used. Maximum Working Pressure (psi): 3000 psi. Bursting Pressure (psi): 10000psi..
【Service】100% satisfaction guarantee, If you have any issues with the part , simply contact customer service for troubleshooting help, parts, replacement, or refund. Our aim is to make you satisfy the parts and the service we provide for you..

HLVP8 single-head high-precision series diaphragm air pump. Series connection flow ≥ 360L/H.
Parallel connection flow ≥ 480L/H, the service life of brush motor is 2000H, and the service life of brushless motor is 6000H..
Parallel negative pressure≥-0.072Mpa, series negative pressure≥-0.088Mpa, positive pressure≥0.1Mpa, noise≤68db..
Using EPDM high-quality diaphragm, it has good resistance to chemicals such as alcohol, acid, alkali, oxidizer, ketone and grease, and poor oil resistance. Good tolerance, dry running, durable, maintenance-free..
Principle: HLVP8 series of miniature diaphragm pumps are simply designed according to the principle of positive displacement pumps. By controlling the inlet and outlet of the diaphragm, a power drive is formed and the transmission mechanism pushes the piston to reciprocate, and the intake pressure pushes the diaphragm back and forth to do work to suck and discharge gas..
Application areas: transmission of gas, inflation, gas analysis, laboratory equipment, fixed objects, household DIY, etc..

HYDROPHOBIC PTFE SYRINGE FILTERS - Virgin PP housing with Hydrophobic PTFE membrane. Diameter: 13mm, Pore Size: 0.22μm, 100Pcs..
UNIFORM PORE SIZE - PTFE Syringe Filter with uniform pore size, high porosity, and high retention efficiency..
PREMIUM PERFERMANCE - It Can be autoclave, sterilize at 121°C/249.8℉ for 45 minutes, it with broad chemical compatibility and strong chemical stability and inertia..
STURDY & DRUABLE - The syringe filters fit well, securely and durable, have reasonable flow for the filtration size, PTFE syringe filters are wall marked, when working with different requirements for filtration to be able to quickly discern which ones are being used..
APPLICATION WIDELY - PTFE Syringe filters are broadly used infiltration of various organic solvents, as well as the filtration of strong acid and strong alkali solutions, perfect for hydrophobic, even such as culture medium, liquid cultures and grain spawn jars..
