Here's a street-smart breakdown of camlock fitting types – the way riggers and pipefitters actually use them on-site:
1. By Gender (Plug/Socket)
| Type | Code | Appearance | Purpose | Killer Weakness |
|---|---|---|---|---|
| Female (Socket) | Type A | Recessed port + cam lever | Tanker outlets, fixed piping | HIGH-PRESSURE GAS → lever ejects |
| Male (Plug) | Type B | Protruding lugs (teeth) | Hose/equipment inlets | Bent lugs → pressure leaks |
| Valved Female | Type FA | Type A + internal spring valve | Drip-free chemical disconnect | Sludge → valve jams |
| Valved Male | Type FB | Type B + poppet valve | Spill-proof fuel disconnect | Rough handling → valve stem bends |
2. By Keying (Mistake-Proofing)
| Type | Code | ID Feature | Stops This Fail |
|---|---|---|---|
| Standard | Type A/B | Universal lugs | Fits all brands (cheap/easy) |
| Anti-Moron | Type C/D | 30° offset lugs | Acid hose → alkali tank |
| Explosion-Proof | Type E/F | Safety-pinned lever + thick lugs | Aviation fuel, flammable zones |
3. By Material (Brutality Rating)
| Material | Brutality | Fear This | Where It Thrives |
|---|---|---|---|
| Aluminum | 3 | Strong acids, hammers | Farms, light oil, water |
| 304 Stainless | 4 | Hydrochloric acid, cost | Food plants, mild chemicals |
| 316 Stainless | 5 | Budget overruns | Seawater, sulfuric crude, chemicals |
| Polypropylene | 2 | Freezing temps, boots | Acids (except HF), labs |
4. By Size (Brute-Force Required)
| Size (inch) | Nickname | Operation Stance | Faceplant Risk |
|---|---|---|---|
| <1" | Toothpick | One-hand flick | Snapped lever → bloody knuckles |
| 2"-3" | Sweet Spot | Stomp hose + back-bend push | Wet hands → jaw strike |
| 4"-6" | Beast Mode | Two-person jump-stomp | Aluminum → permanent dent |
5. Exotic Variants (Niche Solutions)
| Type | Weirdness | Specialized Use | Achilles' Heel |
|---|---|---|---|
| Type DC | Swing gate inside socket | No spill on disconnect | Clogs → 50% flow loss |
| Type M | Recessed cam lever (flush) | Tight spaces | Can't find lever → panic |
| Type AT | Virgin Teflon coated | Ultrapure pharma fluids | $1,000 → scratch = trash |
