PVDF Compression Male Connector for Chemical and Water Treatment Lines
Corroded brass fittings and failed connections cost downtime on chemical dosing and water treatment lines. Jaco Kynar compression tube male connectors solve that problem. Each Kynar PVDF tube fitting uses a PVDF body that handles chlorine, sodium hypochlorite, and strong acids without degrading. This PVDF compression male connector threads directly into an NPT port and seals against the tubing OD. No flaring or soldering required.
Key Features and Benefits
- The PVDF (Kynar) body resists strong acids, halogenated solvents including chlorine and bromine, and aliphatic and aromatic hydrocarbons. A Kynar PVDF tube fitting holds up under continuous chemical exposure where brass or nylon corrodes.
- With the plastic gripper (PG) nut, each PVDF compression male 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 male connectors carry FDA compliance and NSF/ANSI/CAN listing for potable water and food contact. This NSF listed PVDF fitting meets municipal and food-grade purity standards.
- No special tools are needed. Cut tubing squarely, remove burrs, insert through the nut to the tube stop, hand-tighten, and wrench-tighten 1.5 to 2 additional turns.
- PVDF carries a UL V-O fire rating (non-flammable, self-extinguishing) and is autoclavable for lab, pharmaceutical, and food-grade sterilization.

How to Install JACO Kynar Compression Tube Male 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 through the nut assembly until it reaches the tube stop in the fitting body.
- Hold the tubing firmly against the tube stop, then hand-tighten the nut.
- Wrench-tighten the nut an additional 1-1/2 to 2 turns.
- Retighten all nuts when the system reaches its projected operating temperature.
Compression vs Push-to-Connect: Why PVDF Compression Wins in Chemical Service
Jaco Kynar compression tube male connectors seal mechanically between nut, gripper, and body with no elastomer O-rings. Push-to-connect fittings depend on O-rings that swell or dissolve in chlorine, acids, and solvents. PVDF push-to-connect options have become limited, making a chemical resistant compression fitting the practical choice in fluoropolymer.
In PVDF vs brass fittings for chemical lines, brass corrodes and leaches metal ions into ultra-pure systems. A PVDF compression male connector avoids both problems at lower cost than stainless steel.
In chlorine service, shield PVDF fittings from direct sunlight. UV passes through the material and can degrade chlorine compounds in solution.
Pair these Jaco Kynar compression tube male connectors with Jaco Kynar Compression Tube Female Connectors for the opposite threaded connection, or Jaco Kynar Compression Tube Union Connectors for tube-to-tube joints.
Applications
Each PVDF male connector for water treatment and chemical service handles the following applications:
- Municipal water treatment: chlorination, fluoridation, and sodium hypochlorite dosing lines
- Industrial chemical processing: acid transfer, caustic metering, and solvent delivery
- Semiconductor manufacturing: ultra-pure rinse water and chemical distribution
- Pharmaceutical and laboratory: purified water loops and autoclavable fluid connections
- Food and beverage: this NSF listed PVDF fitting meets FDA and NSF/ANSI/CAN requirements for potable water and food-contact piping

Frequently Asked Questions
What is a PVDF compression fitting?
A PVDF compression fitting uses a polyvinylidene fluoride body and nut to connect tubing to a threaded port through mechanical compression. PVDF, sold under the Kynar brand name, resists strong acids, halogens, and hydrocarbons that corrode brass, nylon, and most other plastics.
Are Jaco Kynar fittings FDA NSF certified?
Yes. Jaco Kynar PVDF fittings are FDA compliant for food contact and NSF/ANSI/CAN listed for potable water applications. These certifications confirm the material is non-toxic, does not leach contaminants, and meets the safety requirements for municipal water systems and food processing.
What is the best compression fitting for chlorine dosing systems?
PVDF (Kynar) compression fittings outperform brass, nylon, and stainless steel in chlorine service because the fluoropolymer body does not corrode, pit, or contaminate the chemical stream. Jaco Kynar compression tube male connectors handle sodium hypochlorite and chlorine gas without degradation under continuous flow.
What sizes do Jaco Kynar male connectors come in?
Jaco manufactures Kynar PVDF male connectors in 19 tube-to-pipe combinations, from 1/8" through 7/8" OD tubing with 1/8" through 3/4" NPT thread sizes. Cleanflow stocks eight of the most popular sizes in 1/4", 3/8", and 1/2" OD. Jaco compression fittings Canada buyers can order any stocked size online.
