ELDON JAMES MATERIAL QUICK REFERENCE
Begin by checking the Chemical Resistance Chart. This chart provides a general reference for establishing compatibility between our PVC-free plastic materials and various chemicals. Note: The chart is for reference only – we strongly recommend testing to a standard that takes into account the actual chemical concentrations and environmental conditions specific to your application.

ANTIMICROBIAL PROTECTED (AG)
Antimicrobial protected Ag fittings are available in Nylon, Kynar®, Polypropylene and HDPE with a blue colorant. Natural Ag fittings are 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 Polyvinylidene Fluoride (PVDF) resin features translucent, off-white hemispheres. RoHS compliant 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 includes: 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)
HDPE complies with FDA 21 CFR 177.1520 when used unmodified for the manufacture of food contact articles. HDPE has various applications for use in medical products and devices. It has excellent resistance to chemicals but exhibits lower thermal resistance than other materials. It is a softer material than nylon or polypropylene and much softer than Kynar®. RoHS compliant.
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.
INDUSTRIAL & AUTOMOTIVE MATERIALS
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 lines, vacuum systems, and general-purpose applications. Automotive industry approvals.
Other Approvals:…SAEJ1639PA0172, ASTMD4066PA0181
Temperature Range -50 °F to 275 °F (135 °C) • Pressure 150 psi @ 70 °F
GLASS-FILLED BLACK NYLON (GFBN)
GFBN is a standard material used in automotive and marine under-the-hood, heater and coolant applications. RoHS compliant. GFBN’s enhanced impact resistance results from the inclusion of uniformly dispersed glass fibers that add strength to the resin. Automotive industry approvals.
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.
GRAY POLYPROPYLENE (WP)
Gray 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. Gray Polypropylene fittings are manufactured to the same tolerances and quality standards as our Natural Polypropylene fittings. GP 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 a lot of tractability. RoHS compliant.
