TELESIN Underwater Housing GoPro Hero
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes polycarbonate, rubber seals, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

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.
Rubber seal degradation over time
Elastomer seals lose flexibility and develop micro-cracks after 2-5 years of regular use, saltwater exposure, or UV storage. Degraded seals will no longer provide waterproof integrity and must be replaced to prevent water damage to the camera.
Polycarbonate stress cracking under mechanical impact
Polycarbonate is impact-resistant but can develop stress fractures if dropped sharply or exposed to certain organic solvents (acetone, some solvents in lubricants). Minor cracks may not be visible but compromise waterproof performance.
Mold or bacterial growth in seal cavity
If the case is stored wet or not dried thoroughly after freshwater rinse, moisture trapped in the seal channel can support mold growth. This does not affect the camera if the seal remains intact but is cosmetically unpleasant and indicates maintenance failure.
Optical degradation (fogging, scratching)
The polycarbonate lens window can accumulate internal condensation if temperature differentials are extreme, and external surface scratches reduce underwater image clarity over time. This is a functional issue, not a health hazard.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
Polycarbonate may contain trace BPA as a production residue, but no migration into dry air or food/beverages occurs. This case holds only electronic equipment and poses no ingestion or dermal exposure route.

What it's made of and why it matters
This case is polycarbonate (rigid, transparent thermoplastic) with elastomer rubber seals. Polycarbonate is chemically stable when intact and does not leach into dry air or camera electronics. The rubber seals are the critical component, they create the waterproof barrier and must remain flexible and intact to function. Neither material is known to off-gas or degrade under normal indoor/outdoor use at consumer temperature ranges.
The brand's record and disclosure
GoPro does not publish detailed material safety disclosures for accessory casings on their website. The company has no known recalls or safety controversies specific to this underwater housing model. GoPro's parent company maintains typical consumer electronics standards but offers no third-party certifications (FSC, BPA-free declarations, etc.) for this product category. No public PFAS statements are available from GoPro regarding this case.
How it compares in its category
Polycarbonate housings are the industry standard for action-camera protection because they are durable, optically clear, and resist saltwater and impact better than acrylic alternatives. This TELESIN model is a third-party option competing with GoPro-branded cases; both use similar materials and sealing methods. Compared to silicone or TPU pouches, rigid polycarbonate cases offer better pressure resistance at depth and superior scratch protection.
If you buy it
Rinse the case and seals with fresh water after saltwater use to prevent salt crystallization and rubber degradation. Inspect the rubber seals before each dive for cracks, brittleness, or whitening; replace if visible damage occurs (typically annual for frequent users). Store in a cool, dry place away from direct sunlight to slow rubber aging. Do not expose to prolonged heat above 60 degrees Celsius (140 Fahrenheit), as polycarbonate begins to soften and rubber loses elasticity.
