Prestolok Bulkhead Union for Pneumatic Tube is a TECTUL fluid handling fitting used to pass through boards or sheet metal with pneumatic tube while maintaining push-to-connect fitting on both sides. The lot does not report a single material, so the exact construction must be confirmed when quoting. It differs because it is a panel pass-through for pneumatic tube, not an elbow or a straight union for a free line. The technical selection reference is push-to-connect fitting for pneumatic tube; if the project requires certification, traceability or standard equivalence, request the technical data sheet before installation. To buy it correctly, it is not enough to ask for “the coupling” or “the fitting”: confirm nominal size, end type, fluid, temperature, seal compatibility, available space and whether the assembly works with hose, tubing, NPT thread, quick coupling, camlock system or panel. We do not publish a single maximum pressure because performance depends on material, seal, temperature, vibration, support, joining method, fluid and commissioning test.

We dispatch to Bogotá, Medellín, Cali, Barranquilla and all of Colombia. Request a quote via WhatsApp for this Prestolok bulkhead union for pneumatic tube indicating size, quantity, fluid, connection and use to confirm availability and price.
The price depends on size, material, connection, quantity and availability. At TECTUL we quote using the real installation data to avoid incompatible references.
The Prestolok union joins two tubes in-line; the Prestolok bulkhead union fixes the pass-through in a panel or cabinet.
Tighten the nut against the panel, cut the tube square and push each end fully into the fitting stop.
Send size, quantity, fluid, connection type, a photo if it is a replacement and working conditions when the assembly is critical.
No. Compatibility of the body, seals, gaskets and joining method with the fluid, temperature and line cleanliness must be validated.
Yes. TECTUL dispatches to Bogotá, Medellín, Cali, Barranquilla and other cities in Colombia depending on availability and carrier.

The dimensions, thicknesses, pressures, temperatures and other characteristics stated in this data sheet are theoretical nominal reference values, compiled from publicly available technical sources: international standards (ASME, ASTM, API, MSS, ISO and NTC, depending on the product) and published engineering literature. They are average approximations intended to guide selection, not a certificate of conformity for any given lot.
Actual values may vary due to conditions inherent to the manufacturing process — dimensional and wall-thickness tolerances (in pipe, typically ±12.5%), surface finish and residual stresses from forming or welding — and to factors inherent to the raw material — chemical composition variations within the ranges allowed by the standard, inclusions or heat-to-heat differences. They may also be affected by in-service events not foreseeable at design time: water hammer, vibration, thermal and mechanical fatigue, corrosion and operating overpressures, which can cause the element to fail before its estimated service life.
To know the certified behavior of a specific lot, TECTUL supplies upon request the manufacturer's mill test certificate (MTC) issued per the product standard; for critical applications, laboratory testing of the lot can also be arranged. In the absence of such certification, the data provided here must not be used as the sole criterion in critical or safety applications, or wherever the integrity of the line may compromise the lives of people or property; in such cases, consult our technical team first.
