Gas Bag Fittings

Polypropylene Screw-Cap Combo Valve

Polypropylene Screw-Cap Combo Valve

  • On/Off valve function with replaceable septum in a single unit. Side port for tubing connection.
  • Uses fluoropolymer-faced, low-bleed silicone septum.
  • Inexpensive.
  • Lightweight. Easier to carry multiple bags in the field.
  • Made of inert polypropylene. Ensures sample purity.
  • Quick, easy opening and closing of valve, even in harsh conditions with no tools required. Less than one half turn opens/closes valve.
  • Visual confirmation that valve is open or closed prevents accidental sample loss.
Polypropylene Locking® Combo Valve with Septum

Polypropylene Locking® Combo Valve with Septum

  • On/Off valve function with replaceable septum in a single unit.
  • Uses fluoropolymer-faced, low-bleed silicone septum. Allows repeated punctures with syringes without leakage.
  • Inexpensive.
  • Lightweight. Easier to carry multiple bags in the field.
  • Made of inert polypropylene. Ensures sample purity.
  • Push/Pull (On/Off) valve stem. Quick, easy opening and closing of valve (< 1 second). Faster than "twist-action" valves.
  • Quick locking function requires no tools, and visual confirmation prevents accidental sample loss.
Stainless Steel TCLP Fitting with Septum

Stainless Steel TCLP Fitting with Septum

  • Stainless steel body with aluminum cap and replaceable fluoropolymer faced septum.
  • Durable: withstands use in austere sampling conditions.
  • Inert: Sample contacts only stainless steel & fluoropolymer.
  • Lower cost than 1/4″ Swagelok type fittings and nickel plated Halkey Roberts fitting.
  • Designed for use with Zero Headspace Extractors.
  • Validated fitting style for EPA TCLP (Toxicity Characteristic Leaching Procedure) method.
Stainless Steel Combo Valve with Replaceable Septum

Stainless Steel Combo Valve with Replaceable Septum

  • Design combines on/off valve and septum into a single fitting to lower cost & weight.
  • Stainless steel body with aluminum cap and replaceable fluoropolymer faced septum.
  • Durable: withstands use in austere sampling conditions.
  • Inert: Sample contacts only stainless steel & fluoropolymer.
  • Lower cost than 1/4″ Swagelok type fittings and nickel plated Halkey® Roberts fitting.
Swagelok® type Stainless Steel Fitting for Tubing or Septum

Swagelok® type Stainless Steel Fitting for Tubing or Septum

  • Stainless steel construction. Durability and ability to withstand use in austere sampling conditions.
  • Allows attachment of tubing or syringe sample extraction by switching caps.
  • Replaceable fluoropolymer-faced septum with large area allows repeated punctures with common lab syringes.
Plastic Jaco® Fitting for Tubing or Septum

Plastic Jaco® Fitting for Tubing or Septum

  • Compression ferrule secures tubing onto fitting with superior grip compared to metal fittings.
  • Polypropylene molded construction.
  • Inexpensive compared to metal fittings.
  • Allows attachment of tubing or syringe sample extraction by switching caps.
  • Replaceable fluoropolymer-faced septum with large area allows repeated punctures with common lab syringes.
PFA Fitting for Tubing or Septum

PFA Fitting for Tubing or Septum

  • PFA fluoropolymer construction. Sample only comes into contact with high purity, inert fluoropolymer PFA, the ultimate in chemical resistance and non-contaminating material.
  • Allows attachment of tubing or syringe sample extraction by switching caps.
  • Compression ferrule secures tubing onto fitting with superior grip compared to metal fittings.
  • Replaceable fluoropolymer-faced septum with large area allows repeated punctures with common lab syringes.
Nickel Plated Halkey® Roberts Barbed On/Off Valve

Nickel Plated Halkey® Roberts Barbed On/Off Valve

  • Nickel Plated. Resists damage from most aggressive chemicals.
  • Barbed stem for attaching tubing.
  • Leak resistant seal prevents sample loss in closed position. However, when stem is not closed, sample air passes into ambient air outside valve.
