Description
PVDF Compression Female Connector for Chemical Equipment Ports and Dosing Lines
Metering pump outlets, chemical injection quills, and tank fittings expose male pipe threads that call for a PVDF tubing connection. Jaco Kynar compression tube female connectors thread onto those ports with FNPT threads on one end and compression on the other. This Kynar PVDF tube fitting body withstands chlorine, strong acids, and halogenated solvents. No flaring, soldering, or special tools required.
Key Features and Benefits
- Each PVDF compression female connector threads onto exposed male NPT ports on pumps, valves, and manifolds. The internal pipe thread receives the mating male thread; the opposite end grips tubing by OD through compression.
- The PVDF (Kynar) body is a chemical resistant compression fitting that handles strong acids, chlorine, bromine, and aromatic hydrocarbons. This Kynar PVDF tube fitting holds up where brass corrodes and nylon swells.
- With the plastic gripper (PG) nut, each PVDF compression female connector handles up to 220 PSI and temperatures from -40°F to 250°F. The standard ferrule (O) nut is rated to 50 PSI.
- Jaco Kynar compression tube female connectors are an NSF listed PVDF fitting with FDA compliance for potable water and food contact. Jaco Kynar compression tube union connectors carry the same certifications for tube-to-tube joints.
- PVDF carries a UL V-O fire rating (non-flammable, self-extinguishing) and is autoclavable for lab, pharmaceutical, and food-processing sterilization.

How to Install Jaco Kynar Compression Tube Female Connectors
- Cut the end of the tubing squarely and remove all internal and external burrs.
- Insert the tubing through the back of the nut and continue through the nut assembly until it reaches the tube stop inside the fitting body.
- Hold the tubing firmly against the tube stop and hand-tighten the nut.
- Wrench-tighten the nut an additional 1-1/2 to 2 turns.
- Retighten all nuts after the system reaches its projected operating temperature.
PVDF vs Nylon: Choosing the Right Jaco Fitting Material
Jaco manufactures both PVDF (Kynar) and nylon compression fittings in the same configurations. The choice between PVDF vs nylon fittings for chemical service depends on the fluid. PVDF resists chlorine, bromine, strong acids, and halogenated solvents that attack nylon.
For any line carrying halogens or strong acids, this chemical resistant compression fitting in PVDF is the only Jaco option that holds up. In potable water or RO lines without aggressive chemistry, nylon performs well at lower cost. The Jaco Kynar compression tube male connectors follow the same material logic. Shield PVDF from direct UV in chlorine service, as UV passes through the material and can degrade chlorine compounds.
Applications
A PVDF female connector for water treatment and chemical processing threads onto equipment ports in these applications:
- Chemical metering and dosing: pump discharge ports, injection quills, and control valve outlets on chlorine, fluoride, and acid feed systems. The best compression fitting for chemical dosing pumps uses PVDF to match the chemistry.
- Municipal water treatment: disinfection systems and pH adjustment lines where this NSF listed PVDF fitting meets public water system certification requirements.
- Semiconductor, pharmaceutical, and laboratory: DI water distribution, chemical rinse loops, and autoclavable connections. Kynar fittings FDA NSF certified status meets high-purity and regulatory requirements.
- Food and beverage: CIP manifolds, sanitizer dosing lines, and process piping that requires FDA-compliant contact surfaces.

Frequently Asked Questions
What is a PVDF compression female connector?
A PVDF compression female connector has internal pipe threads on one end and a compression nut on the other. The threads receive a male NPT port while the compression end grips tubing by outside diameter. PVDF (Kynar) resists acids, halogens, and solvents that corrode brass and nylon.
How to connect tubing to a female NPT port?
Apply PTFE tape to the mating male pipe thread. Cut tubing squarely and remove all burrs. Insert the tube through the compression nut to the tube stop inside the fitting body, hand-tighten the nut, then wrench-tighten 1.5 to 2 additional turns. Retighten after the system reaches operating temperature.
Are Jaco Kynar fittings FDA and NSF certified?
Jaco Kynar PVDF fittings are FDA compliant for food contact and NSF/ANSI/CAN listed for potable water. Kynar fittings' FDA NSF certified status confirms the material is non-toxic and meets safety requirements for municipal water systems, food processing, and pharmaceutical applications.
What is the best compression fitting for chemical dosing pumps?
PVDF (Kynar) compression fittings are the standard choice for chemical dosing pump connections. The fluoropolymer body handles chlorine, sodium hypochlorite, fluoride, and mineral acids without corroding. A PVDF compression female connector threads directly onto the pump's male discharge port to connect the dosing tubing.
What sizes do Jaco Kynar female connectors come in?
Jaco manufactures nine Kynar PVDF female connector sizes from 1/4" through 5/8" OD with 1/8" through 1/2" FNPT threads. Cleanflow stocks six sizes in the 220 PSI plastic gripper nut. Jaco compression fittings Canada buyers can order any stocked size online.
