This 40mm gas mask hose is a flexible extension for compatible CBRN masks, respirator hoods, filters and PAPR blowers. It gives more distance between the facepiece and connected filter or blower while keeping the standardized 40mm threaded respiratory connection.
For buyers searching for a gas mask hose, gas mask tubing or PAPR hose, confirm the EN 148-1 / Rd40 interface and complete-system compatibility before use. Thread fit alone does not establish a protection rating.
Fits any gas mask, PAPR hood, or blower with a standard 40mm NATO threaded connection (EN 148-1 / Rd40 / STANAG 4155). Compatible with all CBRNmasks.com masks, hoods, and PAPR systems, including the ONYX 45 PAPR blower, the Israeli 4A1 CBRN Gas Mask, and the Sapphire PAPR Hood for Bearded Men.
Need filters for your gas mask or PAPR system? The Israeli NBC filter is available as a single unit. Easy Breathing 40mm NATO filters are also available in 2-pack, 3-pack, and 4-pack.
Free worldwide shipping. 30-day returns accepted.
A breathing hose can place a compatible filter or powered-air blower farther from the facepiece, which may improve positioning and mobility depending on the complete setup.
Yes. It is intended for compatible 40mm threaded respiratory components. Verify the EN 148-1 / Rd40 interface on every component before use.
It can be used as part of a compatible 40mm powered-air configuration. Confirm the blower, hose, mask or hood, and filter are intended to work together.
No. It is only a connection component. Respiratory protection depends on the complete configured system and suitable filtration.
Fits my setup.
Replaced an old stiff hose with this one. The difference in flexibility is obvious.
Both ends connected cleanly, and the hose bends without feeling flimsy.
The extra hose length moves the filter weight away from my face, which is exactly why I bought it.
Item was like brand new. If I ever need another, I'll come here.

Useful little upgrade. I can keep the canister on my belt instead of hanging it directly from the mask.

Item arrived well packed and ahead of schedule andthe owner was happy to answer any questions about item. More than happy to recommend this store! Only drawback is postage cost, as the US has ways charged ridiculously exorbitant fees.

Bought this hose to fit the matching gas mask, which it does perfectly. No cracks, off smells, or other cons that can happen when buying such items unseen. Great quality!!
The hose uses an EN 148-1 / Rd40 40mm threaded interface. STANAG 4155 is commonly referenced for NATO interoperability. Thread compatibility confirms the mechanical connection, not a filter or protection rating.
It can connect components that use compatible 40mm threaded ports. Check the inlet and outlet on every component and the complete airflow path before assembly.
No. This listing is for the hose extension only. A mask or hood, suitable filter, powered blower, and any other required parts must be obtained separately unless the product page explicitly says otherwise.
It may be used as a replacement where the dimensions and 40mm connections match. Inspect both fittings and the full hose for cuts, crushing, kinks, or deformation before use.
No. A matching thread only establishes connection compatibility. The complete system, airflow, filter selection, wearer interface, condition, and instructions must also be suitable for the intended use.
Keep it clean, dry, uncompressed, and away from direct sunlight, excessive heat, chemicals, and sharp objects. Inspect it again after storage and before assembly.

Everything I expected was in the box. I checked the threads, visor and straps, then did a short fit test at home. Everything was fine.
Factory seal intact, canister clean, no marks. Exactly what I wanted for storage.
Works for me.
Would order again.
Packed it with my camera gear and practiced putting it on quickly. After a couple of tries, the sequence felt natural.

The mask seems well made, but I am still struggling to get the rear straps comfortable around the back of my head. I am keeping it, although the fit has not fully convinced me yet.
Would order again.
