Antimicrobial Protected (AG)
Antimicrobial protected Ag fittings are available in Nylon, Kynar®, Polypropylene and HDPE with a blue colorant. Natural Ag fittings available on select parts. These plastic fittings incorporate natural, non-toxic silver ion protection to guard against microbial colonization and biofilm formation on their surfaces. RoHS compliant. Kynar® Ag fittings (AGNK) are autoclavable.
Natural Kynar® (NK)
Natural Polyvinylidine Fluoride (PVDF) resin features translucent, off-white hemispheres. RoHS complaint and animal derivative free. High stability in harsh thermal, chemical and ultraviolet environments. High toughness and mechanical strength, low permeability, abrasion resistant. NK material can be autoclaved to 285 °F (140 °C) and meets USP Class VI requirements. Generally, these plastic fittings are chemically resistant to: Most acids, salts, weak bases, halogenated solvents, alcohols, nuclear and UV radiation, oxidants, ozone and deionized water.
CrystalVu™ (polyolefin): A clear transparent alternative to polycarbonate containing no Bisphenol-A (BPA). These BPA-free plastic fittings will not deform at temperatures to 180 °C (356 °F). Autoclavable with enhanced characteristics compared to polycarbonate that include: Superior chemical resistance, no crazing with multiple autoclave cycles, plus gamma and EtO Sterilization compatibility. RoHS compliant, USP Class VI, EU 2002/72/EC.
High Density Polyethylene (HDPE)
Nylon - Natural (NN) / Medical (MN)
Nylons exhibit good tensile strength, moderate stiffness and high impact resistance. They’re resistant to fuels, lubricants and many chemicals, but vulnerable to attack by phenols, strong acids and oxidizing agents. MN White Medical Nylon is made from the same resin as Natural Nylon, but has an FDA compliant white colorant added. RoHS compliant.
Animal Derivative Free Polypropylene (PP)
A polypropylene formulated for biomedical and bioprocess applications. Meets FDA requirements 21 CFR 177.1520(a)(3)(i) and (c)3.1a. PP material has a Drug Master File listing and is RoHS compliant. It is radiation stable and is resistant to solvents, chemicals, water and other inorganic environments. It resists most strong mineral acids and bases; however, it is subject to attack by oxidizing agents.
Black Nylon (BN)
Made from 6/6 nylon, black nylon fittings exhibit strength, moderate stiffness, high service temperature, high impact resistance and tensile strength. Resistant to fuels, lubricants and many chemicals, but vulnerable to attack by phenols, strong acids and oxidizing agents. RoHS compliant. Used in fuel line, vacuum systems and general purpose applications. Automotive industry approvals.

Temperature Range -50 °F to 275 °F (135 °C) • Pressure 150 psi @ 70 °F
Glass-Filled Black Nylon (GFBN)
Temperature Range -50 °F to 275 °F (135 °C) • Pressure 150 psi @ 70 °F Heat Deflection Temperature – ASTM D64: 475 °F (246 °C) @ 264 psi
Stainless Steel (SS)
Fittings produced with 316L alloy perform well in high temperature, harsh physical environments. 316L molybdenum bearing stainless steel has excellent impact and chemical resistance, but is less resistant than other types of stainless steel to highly oxidizing acids, such as nitric acid. RoHS compliant. The material has wide application in pharmaceutical and dairy processing and is used extensively for fittings in the brewery, beverage and bioprocess industries.
White Polypropylene (WP)
White Polypropylene has the same physical and chemical resistance properties as Natural Polypropylene, but is less expensive. WP fittings contain recycled runner material produced during virgin material, Natural Polypropylene production runs. White Polypropylene fittings are manufactured to the same tolerances and quality standards as our Natural Polypropylene fittings. WP is not a USP Class VI material and does not offer lot tractability. RoHS compliant.
White Nylon (WN)
White Nylon has the same chemical and physical properties as Natural Nylon. WN fittings contain recycled runner material produced during virgin material, Natural Nylon production runs. White Nylon fittings are manufactured to the same tolerances and quality standards as our Natural Nylon fittings. WN and does not offer lot tractability. RoHS compliant.
Gray Kynar (PVDF)
Gray Polyvinylidine Fluoride (PVDF) fittings exhibit the same physical and chemical resistance properties as Natural Kynar®. PVDF fittings contain recycled runner material produced during virgin material, Natural Kynar® production runs. For applications that do not require lot tractability or a material that meets USP Class VI requirements, PVDF fittings represent an excellent value. RoHS compliant.
