Are there any concerns about corrosion due to harsh environments, cleaners or off-gassing of produce/vegetables?

RLS fittings have gone through extensive SWATT testing, completing over 2,000 hours of salt spray testing without failure, which proves the resilience of the product. Care should be given to avoid areas that could be exposed to ammonia or ammonia-like substances, as ammonia is very corrosive to copper fittings and tubing.
