🔍 Key Concepts

• Oil transfer hose flange requirements in 46 CFR (look for rules on fuel or oil transfer hoses and their connections) • The difference between a minimum number of bolts and a requirement that all bolt holes be used • Why uniform gasket compression and leak prevention matter for oil flanges

💭 Think About

• Is the regulation written as a specific number of bolts, or does it describe how the flange must be bolted (for example, something about every bolt hole)? • If a flange has 8 holes, would using only 3, 4, or 6 bolts give even pressure and a good seal for oil transfer? What might the regulation require to prevent leaks? • When regulations talk about "permanently connected" flanges on oil hoses, are they more concerned with ease of disconnection, or with maximum tightness and security?

✅ Before You Answer

• Check 46 CFR sections dealing with oil/fuel transfer hoses and couplings for exact wording on flange connections. • Verify whether the rule specifies a fixed minimum count (like 3, 4, or 6) or requires all available flange holes to be bolted. • Confirm that the intent of the rule is leak prevention and structural integrity, which influences how many bolts are acceptable.
