What is tubing union ?

Union connectors supplied by PTFE union manufacturers is a type of PTFE Tube Compression Fittings. PTFE which is also known as Polytetrafluoroethylene Union. A fluorocarbon-based polymer used in PTFE UNIONis a resin supplied in powdered form, which is mixed, preformed, and extruded into a paste, and then finally tubing., , Stainless steel bulkhead fitting is available in 1/8″ OD Tube,1/4″ OD Tube,3/8″ OD Tube ,1/2″ OD Tube . They are also available in metric system from size 4mm OD Tube , 6mm OD Tube , 8 mm OD Tube ,10 mm OD Tube ,12 mm OD Tube.PTFE Bulkhead Union is a type of polypropylene bulkhead tank fitting. PTFE Bulkhead Union can be used in a large variety of applications due to its high chemical resistance, high and low temperature capability, resistance to weathering, electrical &thermal insulation, and lowest coefficient of friction of any solid material. The PTFE union fittings are translucent white in color.

    Category (Name)
    Melting Point and Operating Temperature
    Chemical Resistance
    PTFE
    m.p. 327oC, W.TEMP(MAX) 260oC

    Excellent chemical stability;, PTFE don't interact with the vast majority of chemicals and solvents., However, it is vulnerable to molten alkali metal., PTFE also interacts with fluorine gas and fluorine compounds, such as CIF3. OF2, under high temperature and high pressure environments

    ETFE
    m.p. 270oC, W.TEMP(MAX) 150oC

    Similar to the chemical resistance of PTFE, but easily corroded by nitric acids. Has chemical resistance on par with PTFE, but easily corroded by certain chemicals such as nitric acid.

    PCTFE
    m.p. 327oC, W.TEMP(MAX) 260oC

    Highly crystalline, high polymer material, with superior permeability properties. 

    PFA
    m.p. 327oC, W.TEMP(MAX) 260oC

    Similar to the chemical resistance of PTFE, with superior mechanical and sanitary properties.

    FEP
    m.p. 327oC, W.TEMP(MAX) 260oC
    Similar to the chemical resistance of PTFE, but has slightly lower operating temperature.
    PVDF
    m.p. 327oC, W.TEMP(MAX) 170oC

    Easily dissolved by fuming sulfuric acid, high temperature sulfuric acid, or caustic soda above 100oC; also bloats or dissolves when interacting with strong solvents such as aceton、ketone、DMA, or extremely alkalic primary amine such as n-butylamine.

    sms union ptfe gasket Applications

All Straight compression union fittings are made from natural virgin materials. To maximize creep resistance, our PTFE bulkhead fittings are made from low-creep virgin PTFE. Standard PVC bulkhead fitting are supplied with FEP-encapsulated hollow-core silicone o-rings. PFA encapsulated hollow-core silicone o-rings, PFA encapsulated Viton, or other o-ring materials can be supplied.

PolytetrafluoroethylenePTFE Bulkhead Connectors are a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. The best known brand name of PTFE-based formulas is Teflon. It is a spin-off of DuPont, which originally discovered the compound in 1938

Tank adapters allow quick, easy connection of Schedule 80 PTFE threaded pipe system, or any NPT pipe system to tanks of any material- plastic, metal, or lined. PTFE Bulkhead Fittingscan be installed without adapters in either flat wall tanks, or many cylindrical tanks. PTFE fittings have NPT connections.Fittings are also available in PVDF. The PVDF fittings are available with both NPT and socket weld connections.

Compression bulkhead union is a fluorocarbon solid, as it is a high-molecular-weight compound consisting wholly of carbon and fluorine. PTFE possesses hydrophobicproperty which means neither water nor water-containing substances can wet PTFE, as fluorocarbons demonstrate mitigated dispersion forces due to the high electronegativity of fluorine. PTFE union equipment has one of the lowest coefficients of friction of any solid.
