WC Safety Editorial Pick: The PA031L is the large-size replacement breathing tube for Honeywell North PA700-series PAPR systems — the component that gets the most physical wear in day-to-day use and should be inspected and replaced on a regular maintenance schedule.
The Honeywell PA031L is the large (long) breathing tube designed for use with the PA700-series belt-worn PAPR systems. The breathing tube routes filtered air from the blower motor at the waist to the face-piece, and in that role it endures constant flexing, UV exposure, and the mechanical stress of regular donning and doffing. Replacing a cracked or degraded breathing tube is one of the most frequently overlooked steps in PAPR maintenance programs, yet a compromised tube can allow unfiltered air to bypass the respirator entirely.
The PA031L is specifically the large-size variant, suited for taller workers or configurations requiring a longer tube run between the belt unit and the headtop. The 'L' designation matters when ordering — the shorter PA031S fits smaller workers and certain headtop configurations. Honeywell recommends annual breathing tube replacement as a minimum, with more frequent replacement if the tube shows any visible cracking, discoloration, or deformation at the connection fittings.
Facilities running Honeywell North PA700 or PA701 series PAPR systems should stock spare breathing tubes as part of their standard PPE inventory. Tube failure is a foreseeable event with a simple fix — a bag of spare PA031L tubes prevents production downtime when a tube fails mid-shift. The tube connects to the blower outlet and the face-piece adapter using the standard Honeywell North bayonet fittings, requiring no tools for replacement in the field.

Frequently Asked Questions
What PAPR systems is the PA031L compatible with?
The PA031L is designed for use with the Honeywell North PA700 and PA701 series belt-worn PAPR blowers. Verify connector compatibility before ordering for other Honeywell models.
What is the difference between PA031L and PA031S?
PA031L is the large (long) size breathing tube for taller workers or configurations needing more tube length between the blower and face-piece. PA031S is the shorter small/medium variant. Always match tube length to your worker's size to avoid excess drape or tightness.
How often should I replace the PAPR breathing tube?
Honeywell recommends replacing breathing tubes at a minimum annually. Replace immediately if you observe any cracking, discoloration, stiffening, or damage at the connection fittings — a compromised tube can allow unfiltered air to bypass the respirator system.
Can I reuse or patch a cracked breathing tube?
No. Do not patch or tape a damaged breathing tube. A cracked or compromised tube must be replaced immediately, as air leaks can negate the respiratory protection the PAPR system is designed to provide.
How do I connect the PA031L to the PA700 blower?
The PA031L uses Honeywell North's standard bayonet fitting — insert the tube end into the blower outlet and turn to lock. The connection requires no tools and should click positively into place.
Is the PA031L sold as a single tube or in a multipack?
The PA031L is sold as an individual replacement tube. Order multiple units to maintain inventory for maintenance programs.
What material is the PA031L breathing tube made from?
The tube is constructed from a corrugated flexible polymer that withstands continuous flexion during normal PAPR use without kinking or collapsing.
Does the PA031L work with Honeywell North full-face respirators?
The PA031L connects to the PAPR blower side. Compatibility with the face-piece end depends on the specific face-piece and adapter. Consult Honeywell's current compatibility chart for your North full-face or half-face model.
How do I clean the PA031L breathing tube?
Flush the tube interior with warm water and approved disinfectant solution, then allow to air dry thoroughly before storage. Do not use abrasive cleaners that could damage the tube interior.
Is the PA031L covered by Honeywell warranty?
As a replacement part, the PA031L is subject to Honeywell's standard parts warranty. Contact Honeywell Safety Products directly for warranty claims on replacement components.
Can the breathing tube affect PAPR airflow readings?
A kinked, blocked, or excessively long breathing tube can restrict airflow. Always ensure the tube is free of kinks during use, and verify that your blower's flow indicator confirms adequate airflow before entering the hazard area.
What is the PAPR assigned protection factor when using the PA031L with the PA700?
The PA031L itself does not determine the APF — it is the blower, filter, and face-piece combination that establishes protection level. Consult OSHA 1910.134 Table 1 and your respiratory protection program for the complete system APF.
