While it is true that the Teflon PTFE paste used to make high grade hose is a premium material, the hose itself is often a more economical choice than traditional products when total lifecycle-cost is considered. There are a number of factors to consider when comparing hose acquisition cost and performance. Cost - In almost all cases a hose made with Teflon will outlast an ordinary rubber or thermoplastic hose under virtually any operating condition. But whether this factor alone is enough to justify the higher initial acquisition cost of a hose made with Teflon will vary from application to application; in most cases the answer will be "no". However, that begins to change when costs other than the initial purchase price are considered - particularly costs related to downtime, contamination and effusion. A Teflon fluoropolymer hose core will inhibit the accumulation of contaminants, the loosening of which may cause damage to downstream equipment, for example.
