Chemical Resistant Tubing and Fittings
Cleanflow stocks chemical resistant tubing and the compression fittings that join it, for feed lines that carry acids, alkalis, sodium hypochlorite and other corrosive chemicals.
The tubing is NSF 51/61 and FDA-compliant polyethylene (LLDPE, HDPE and LDPE), PTFE and clear vinyl, 1/4 in. to 1 in. OD. The chemical resistant fittings are Jaco compression connectors, unions, tees and elbows in Kynar (PVDF) or nylon, plus a Kynar check valve and tubing support clamps. All of it ships from Winnipeg across Canada.
How to Choose Chemical Resistant Tubing
Pick the tubing by the chemical it carries and the line temperature, then order fittings to match the tubing OD.
-
NSF 51/61 LLDPE. Flexible polyethylene for potable water, beverage and most chemical feed lines, and the one to use where the line bends. 1/4, 3/8 and 1/2 in. OD in 100 ft rolls or 500 ft coils. Rated to 180 °F.
-
NSF 51/61 HDPE. Stiffer polyethylene for sodium hypochlorite, concentrated acids and strong alkalis at higher pressure than LDPE. 1/4, 3/8 and 1/2 in. OD in 100 ft rolls. Rated to 151 °F.
-
Coloured LDPE (blue, yellow, red, green). FDA-approved polyethylene for colour-coding chlorine, pH and coagulant lines. 1/4, 3/8 and 1/2 in. OD, limited sizes. -40 °F to 158 °F.
-
PTFE (Teflon). For solvents, concentrated acids and hot lines that attack polyethylene. 1/4, 3/8 and 1/2 in. OD by the foot or 500 ft roll. -328 °F to 500 °F.
-
Clear vinyl. Low-pressure water, air and mild chemical lines where you need to see the flow. 1/4 in. to 1 in. OD. 23 °F to 158 °F.
Fitting materials: nylon or Kynar
-
Nylon: Known for its toughness and resilience, nylon fittings are lightweight and resistant to abrasion, making them suitable for applications involving mild acids, alkalis, and oils. Nylon is also an excellent choice for general-purpose systems due to its mechanical strength and flexibility. Jaco nylon compression fittings are FDA and NSF listed and rated for 220 PSI from -40 °F to 250 °F.
-
Kynar (PVDF): Ideal for more aggressive environments, Kynar offers superior resistance to a wide range of harsh chemicals, including strong acids, solvents, and chlorine. This material is also highly resistant to UV radiation and weathering, making it perfect for outdoor and high-temperature applications. Jaco Kynar compression fittings carry the same 220 PSI and -40 °F to 250 °F rating and are the choice for sodium hypochlorite and acid feed lines.
Sizing the fittings
Jaco compression fittings are sized by tube OD, not by thread: a 3/8 in. fitting takes 3/8 in. OD tubing. Male and female connectors, union connectors, union elbows, union tees, male branch tees and male run tees cover every joint on a feed line, in 1/4 in. to 7/8 in. OD. The tube end seats on a gripper and sleeve, so no flaring or tools are needed and the joint can be remade. Where the line needs backflow protection, the Jaco Kynar PVDF check valve has a Hastelloy C spring, PTFE ball and Viton O-ring and is rated to 180 °F and 220 PSI.
Where this tubing goes
-
Chemical feed lines. Suction and discharge tubing between a day tank, a chemical metering pump or injection pump, and the injection point. Most pumps take 1/4 in. or 3/8 in. OD tubing with compression connections.
-
Water and wastewater treatment. Sodium hypochlorite, soda ash, coagulant and polymer feeds; sample lines to analyzers.
-
Food, beverage and potable water. NSF 51/61 polyethylene and food grade vinyl or PTFE for lines that touch product.
-
Labs and pilot plants. Acid resistant tubing and PTFE for reagent and solvent transfer.
Chemical Resistant Fittings and Tubing in Stock
Jaco Kynar Compression Tube Union Tees
Jaco Kynar Compression Tube Union Tees join three runs of tubing of the same OD. Kynar (PVDF) body for acids, chlorine and hypochlorite, compression ends on all three legs, 220 PSI at -40 °F to 250 °F.
Jaco Kynar Compression Tube Union Elbows
Jaco Kynar Compression Tube Union Elbows turn a tubing run 90 degrees in a tight space. Same Kynar body and compression ends as the tees, same 220 PSI rating. Nylon versions of both, and of the straight connectors, are stocked for milder chemicals.

Buy Chemical Resistant Tubing and Fittings Online from Cleanflow
Every chemical resistant tubing size and Jaco fitting on this page ships from Cleanflow's Winnipeg warehouse across Canada. Tubing is sold by the foot, roll or coil and fittings by the piece or pack, so a full feed line, from tank to injection point, can go out in one order. Not sure whether your chemical needs nylon, Kynar or PTFE? Email the chemical name and concentration to info@cleanflow.ca and we will confirm the compatible tubing and fittings before you order. Drum pumps, scoops and storage tanks for the same chemicals are under chemical handling; the full Jaco range is under Jaco.
Frequently Asked Questions
How do I choose the right tube fitting?
Evaluate factors such as chemical compatibility, pressure rating, tube size, and application needs. Match the fitting to the tube OD, then pick Kynar for aggressive chemicals and nylon for mild ones; each product page lists the pressure and temperature rating.
Are these fittings suitable for outdoor use?
Yes, materials like Kynar and HDPE tubing provide excellent UV resistance and durability for outdoor applications.
Which tubing is chemically resistant to sodium hypochlorite?
NSF 51/61 HDPE and LLDPE polyethylene tubing both carry sodium hypochlorite; HDPE is the stiffer, higher-pressure option. Use Kynar (PVDF) compression fittings on the line, not nylon, because chlorine attacks nylon over time.
Nylon or Kynar fittings: which do I need?
Both are rated 220 PSI from -40 °F to 250 °F. Nylon suits water, mild acids, alkalis and oils and costs less. Kynar handles strong acids, solvents, chlorine and hypochlorite. If the chemical is on the aggressive side, choose Kynar.
What size tubing do the compression fittings take?
Jaco fittings are stocked from 1/4 in. to 7/8 in. OD, with 1/4, 3/8 and 1/2 in. in most configurations. Those three sizes match the polyethylene tubing on this page and the connections on most chemical metering pumps. Order the fitting by the tube OD printed on the tubing, and the thread (MPT or FPT) on the pump or valve it joins.
