Nationalpresto Presto Pressure Cooker and Canner 01755
Low-medium risk. Stainless steel pressure canner with no nonstick coating or known PFAS treatments.
The 01755 is stainless steel with no nonstick surface, removing the primary PFAS risk vector in cookware. Presto makes no PFAS claims or disclosures.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Gasket and sealing material degradation
Silicone and rubber gaskets can harden, swell, or lose elasticity after repeated high-heat cycles or exposure to acidic foods. Degraded seals compromise pressure safety and can allow steam escape. Replacement gaskets are inexpensive and widely available, and failure is signaled by visible deformation or persistent steam leaks.
Stainless steel corrosion and leaching under acidic or salt conditions
Prolonged contact with high-salt or highly acidic foods (vinegar, citrus, tomato) can initiate pitting corrosion in stainless steel, though risk is low at typical home cooking exposures and durations. Canning with salt-heavy brines or vinegar-based recipes should not exceed normal processing times. No heavy-metal release is expected even with corrosion.
What’s reassuring
Bare uncoated material
Recorded as a bare, uncoated material with no surface coating or treatment.
Aluminum leaching (not applicable)
This model is stainless steel, not aluminum. No aluminum leaching risk.
Lead
Stainless steel body has no enamel, ceramic, or glaze coating. Interior and exterior are bare metal. No lead or cadmium hazard from coatings.
Source, ATSDR ↗Teflon-type coating fume risk (nonstick coating toxicity)
This model has no Teflon-type coating (Teflon) or other non-stick polymer coating. No risk of polymer fume release, even at high temperature or if scratched.
The full breakdown
What it's made of and why it matters
The Presto 01755 uses 18/10 stainless steel (304-grade) for the main body and lid, which is chemically inert and does not leach metals into food under normal pressure-cooking conditions. Unlike non-stick coated cookware, stainless steel has no polymer coatings that degrade, flake, or release fumes when heated. The gasket and sealing components are typically silicone or rubber, which are stable at the operating temperatures of a pressure cooker (around 250F at 15 psi).
The brand's record and disclosure
Presto has manufactured pressure cookers for over 80 years with no major recalls linked to material toxicity or coating degradation. The company does not publicly detail PFAS treatment of any components, but the absence of non-stick coatings makes intentional PFAS use unlikely in this model. Presto has not sought third-party certifications (NSF, FDA pre-approval testing) for this product, but stainless steel cookware does not require them under current U.S. regulations.
How it compares in its category
This model represents a lower concern design for pressure cookers, bare stainless steel with no coating. Competing brands (All American, Fagor) use similar materials. Non-stick pressure cookers exist but are less common and pose higher coating-degradation risk. The 01755 avoids the hazards of ceramic-coated or aluminum pressure cookers, which can leach or corrode over time.
If you buy it
Hand-wash rather than dishwasher-wash to avoid aggressive alkaline detergents that can etch stainless steel over decades, though this does not pose a safety risk. Replace the rubber gasket every 1-2 years or if it becomes hard or sticky, as seal failure is the primary maintenance issue. Do not use abrasive scouring pads on the interior, as scratches can create crevices where bacteria survive. Avoid prolonged contact with salt water (brine pickling), as chlorides can initiate stress-corrosion cracking in stainless steel, though this is rare at home use levels.
