Honeywell PA031L PAPR Breathing Tube Review — PA-Series Replacement Part
Is the Honeywell PA031L the right breathing tube for my PA-Series PAPR?
Short answer: Yes, if you are running a Honeywell PA-Series PAPR — the PA031L is the manufacturer-specified replacement breathing tube, maintaining NIOSH approval and the correct fit between headtop and blower unit.
Honeywell PA031L PAPR Breathing Tube Review (2026)
Breathing tubes on powered air-purifying respirators are wear items: they crack, degrade from disinfectant exposure, and accumulate biological contamination over a PAPR program's service life. The PA031L is Honeywell's replacement tube for the PA-Series, including the PA701HED PAPR system. This review covers fit, compatibility, and the maintenance use case. Full PAPR selection guidance is in our 3M Respiratory Protection Buyer's Guide.
Editorial verdict — 4.2/5
The PA031L earns 4.2/5 as a straightforward OEM replacement part: correct fit, maintains system NIOSH approval, and eliminates the compatibility risk of aftermarket tubes. Buy when the existing tube is damaged, discolored, cracked, or has accumulated biological contamination that cannot be adequately decontaminated.VIEW ON WC SAFETY →CHECK PRICE ON AMAZON →

Who it is for
- Facilities running Honeywell PA701HED PAPRs on multi-user or decon-cycle programs needing replacement breathing tubes
- Safety managers maintaining a PAPR fleet and stocking OEM spare parts
- Programs using the PA700 decon kit who need breathing tube replacements as a separate line item
What the PA031L does well
OEM fit maintains NIOSH approval
Using the PA031L rather than an aftermarket tube ensures the PA-Series system stays within its NIOSH-approved configuration under 42 CFR Part 84. See our respiratory protection guide for why approval compliance matters under OSHA 1910.134.
Critical maintenance item for decon programs
The breathing tube is among the highest-contact components in a PAPR — it routes exhaled and inhaled air between blower and headtop and is exposed to disinfectant solutions during cleaning cycles. Stocking spares prevents program downtime when a tube must be replaced mid-shift.
Low per-unit cost for a high-leverage part
Relative to the blower unit, the PA031L is an inexpensive wear item. Facilities that stock one or two spares per active PAPR unit eliminate the downtime risk of a single tube failure taking a blower out of service.
Where the PA031L falls short
Single-component scope
The PA031L replaces the breathing tube only. If the headtop or blower also needs replacement, the PA700 decon kit or the full PA701HED starter kit are the appropriate options.
PA-Series only
Not compatible with Drager X-plore 8500, MIRA Safety MB-90, or other PAPR platforms. Confirm the blower model before ordering.

When to step up from the PA031L
If the headtop is also compromised, buy the PA700 decon kit which includes the breathing tube, headtop components, and valve parts as a single restocking event. For a complete PAPR system, see the PA701HED PAPR Starter Kit.
Category context
Breathing tube replacement is part of the routine maintenance lifecycle for PAPR programs. Under OSHA 1910.134, employers must establish maintenance and inspection procedures for all supplied-air and powered-air respirators. The PA031L addresses the tube component of that obligation for PA-Series PAPR programs. See respirator fit testing and PAPRs for beard wearers for the use cases that drive PA-Series adoption.
Total cost of ownership
The PA031L is a consumable cost in the PAPR maintenance budget. Per-unit tube cost is low relative to the blower; the relevant TCO question is stocking quantity and replacement trigger. Many programs replace breathing tubes on a defined cycle (e.g., every 6 months or after each decon campaign) rather than waiting for visible failure.
Final verdict
The PA031L earns 4.2/5 as the correct OEM tube for PA-Series PAPR maintenance. Stock it as a spare, replace on program schedule, and combine with the PA700 decon kit for a complete decon-cycle restocking approach.

PA031L FAQ
What PAPR is the Honeywell PA031L breathing tube compatible with?
The PA031L is designed for Honeywell PA-Series PAPR systems, including the PA701HED starter kit. It is not cross-compatible with other PAPR platforms.
How often should I replace the PA031L breathing tube?
Follow your facility's written respiratory protection program. Common triggers include visible cracks, discoloration, persistent odor after cleaning, loss of elasticity, or a defined time-in-service interval (often 6–12 months depending on use frequency).
Does the PA031L maintain NIOSH approval?
Using OEM replacement components like the PA031L in the approved PA-Series PAPR configuration maintains the system's NIOSH approval under 42 CFR Part 84. Aftermarket tubes may not maintain this compliance.
Can I disinfect the PA031L breathing tube?
Yes — follow Honeywell's recommended cleaning and disinfection procedure for PA-Series components. Repeated disinfectant exposure will cause gradual degradation; inspect for cracking or stiffness after each cleaning cycle.
What is the difference between the PA031L and the PA700 decon kit?
The PA700 decon kit includes the breathing tube, headtop components, and valve parts as a bundled restocking kit. The PA031L is the tube alone — the right choice when only the tube needs replacement.
Is the PA031L tube the same as what comes with the PA701HED?
The PA031L is the replacement breathing tube compatible with the PA-Series; confirm against your PA701HED documentation to verify the exact part number match for your specific blower model.
Can I use a third-party breathing tube with my Honeywell PAPR?
Third-party tubes may not maintain NIOSH system approval and can create fit or flow-path issues. OEM replacement with the PA031L is the recommended approach.
What should I inspect on the PA031L before each use?
Inspect for cracks, tears, stiffness, unusual odor, and secure connection at both ends (headtop and blower). A compromised tube can reduce airflow or allow unfiltered air to enter.
How do I connect the PA031L to the PA-Series PAPR?
Follow the PA-Series assembly instructions: the tube connects at the blower outlet and headtop inlet with the manufacturer-specified fittings. Verify positive connection and no gaps before use.
Is a PA-Series PAPR right for chemical hazards?
With appropriate combination filters, PA-Series PAPRs can provide chemical vapor protection. The PA031L breathing tube is a passive component — protection depends on the filter/cartridge combination approved for the blower.
Where can I buy spare PA031L breathing tubes?
Via the Amazon link above or through our PAPR accessories catalog for related components.
How does a breathing tube failure affect PAPR protection?
A cracked or improperly connected breathing tube can allow ambient (unfiltered) air to bypass the filter and reach the headtop, breaking the protection chain. This is why routine tube inspection is a required step in any written respiratory protection program.
Does the PA031L work with all PA-Series filter types?
The breathing tube is filter-agnostic — it routes airflow between blower and headtop regardless of the installed filter type. Ensure the filter-blower-tube-headtop combination is all PA-Series approved components.
Can the PA031L be used in a healthcare infection control setting?
Yes — PA-Series PAPRs including the PA031L breathing tube are used in healthcare infection control settings. Follow your facility's IPC protocol for headtop and breathing tube decontamination or replacement cadence.
What size is the PA031L?
The PA031L is sized for the PA-Series PAPR blower and headtop fittings. Confirm compatibility with your specific PA-Series model using the Honeywell PA700/PA701 documentation before ordering.
