Valves, lids
& fittings.
Short answer
- S60 and S100 buttress threads do not mate with NPT
- Garden-hose adapter is our single most-ordered item
- Vented lids for hot fill and pump draw-down; solid for storage
- No minimum order on parts

The thread chart
Everything that screws into an IBC
Print this. Half the fittings sold for IBC totes are the wrong thread form, and the damage is usually done before anyone notices.
| Size / item | Type | Thread | Cap or plug | Typical use |
|---|---|---|---|---|
| DN50 / 2 in | Butterfly, polypropylene body | S60×6 buttress outlet | 2 in NPT or S60 dust cap | Most common on 275/330 composite totes |
| DN80 / 3 in | Butterfly, PP or PE body | S100×8 buttress outlet | 3 in or S100 cap | Faster discharge, viscous product, ex-food totes |
| DN50 ball | Full-port ball valve | 2 in BSP / NPT | Threaded plug | Retrofit for throttling and dosing |
| 6 in lid | Screw cap, vented or solid | 6 in / 150 mm coarse | EPDM or silicone gasket | Top fill port on nearly every composite IBC |
| 9 in lid | Screw cap | 9 in / 225 mm coarse | EPDM gasket | Older bottles and some rigid poly tanks |
| Camlock adapter | Type A/C/F polypropylene | S60 or S100 to 2 in cam | Dust plug | Hose-quick-connect for transfer pumps |
| Garden-hose adapter | Brass or nylon | S60 to 3/4 in GHT | — | Rain harvesting, irrigation, wash-down |
| Gasket set | EPDM / Viton / silicone | — | — | Replace on every rebottle; the #1 source of weep leaks |
Short answer
- S60×6 = 2 in / DN50 outlet (most common)
- S100×8 = 3 in / DN80 outlet
- 6 in lid = 150 mm coarse thread
- NPT and BSP never mate with buttress — use an adapter
Gasket selection
Nine dollars of rubber, or a weeping tote for two years
| Compound | Temperature range | Good for | Fails with |
|---|---|---|---|
| EPDM | −40 to 120 °C | Water, aqueous chemistry, caustics, dilute acids, most food duty | Aromatics, solvents, fuels, oils |
| Viton (FKM) | −20 to 200 °C | Aromatics, chlorinated solvents, fuels, oils, esters, ketones | Hot water above 130 °C, ketones at high concentration, amines |
| Silicone (platinum-cure) | −60 to 230 °C | Hot-fill food, steam exposure, high-purity duty | Solvents, oils, abrasion |
| Nitrile (NBR) | −30 to 100 °C | Petroleum products, vegetable oils, greases | Ozone, sunlight, strong oxidisers |
| PTFE-envelope | −200 to 260 °C | Almost everything, including strong acids | Cost, and it will not take repeated re-torquing |
If you are not sure, tell us the product name in your request and we will specify it. Gasket compatibility is one of the few questions in this trade with a genuinely correct answer.
Popular items
What people actually order
S60 to garden hose adapter
$12 – $19. Brass or nylon. Turns any tote into a gravity-fed water source. Brass if it lives in the sun — UV embrittles nylon within two seasons.
DN50 butterfly valve, PP body
$28 – $46. Direct replacement for the standard outlet valve, supplied with a new gasket. The commonest single repair on a used tote.
Camlock adapter set
$24 – $58. Type A, C and F in polypropylene, buttress to 2-inch cam. For transfer pumps and quick changeover between totes.
6-inch lid, solid or vented
$14 – $27. With a new gasket. Specify vented for hot fill and pump draw-down, solid for storage and regulated shipping.
Gasket packs
$9 – $22 each, cheaper in tens. EPDM, Viton, silicone and nitrile. Buy a strip of ten and keep them on a hook by the pump.
Full-port ball valve retrofit
$62 – $145. When you need throttling or dosing control rather than open-or-shut. Fits the standard S60 or S100 outlet.

Questions
Parts questions
What thread does an IBC tote outlet use?
A coarse asymmetric buttress thread, not a pipe thread. DN50 outlets are S60×6 and DN80 outlets are S100×8. These do not interchange with NPT or BSP, which is why adapters exist and why forcing an NPT fitting into an S60 outlet ruins both parts.
Which gasket material should I use?
EPDM for water, aqueous chemistry and most food duty. Viton for aromatics, solvents, fuels and anything containing esters or ketones. Platinum-cure silicone for high-temperature food applications. A wrong gasket is the single most common cause of a weeping valve, and it costs about nine dollars to get right.
Can I fit a garden hose to an IBC tote?
Yes — an S60 to 3/4-inch GHT adapter in brass or nylon costs under $20 and is the most-ordered single item in this catalogue. Nylon is fine for water; use brass if the tote sits in direct sun, because UV embrittles nylon within a couple of seasons.
Should I use a vented or solid lid?
Vented for hot fill, for anything that off-gasses, and for product you are drawing down with a pump that would otherwise collapse the bottle. Solid for storage, for potable water and for any regulated shipment. Fitting a vented lid to a stored potable tote is how you get insects and algae.
Do you sell parts in small quantities?
Yes. One gasket, one valve, one adapter. We would rather sell you a nine-dollar part that fixes your tote than a two-hundred-dollar tote that replaces it.
Ordering by symptom
Start from the problem, not the part number
Most parts enquiries arrive as a description of something going wrong. This is the translation table our own counter uses.
| What is happening | Most likely cause | Part to order | Cost |
|---|---|---|---|
| Weep at the valve after refitting | Gasket extruded by over-torquing | New valve gasket, correct compound | $9 – $22 |
| Weep that returns after every wash | Wrong gasket compound for the product | Gasket in a compatible compound | $9 – $26 |
| Valve will not close fully | Worn disc seat or debris | New DN50 or DN80 butterfly valve | $28 – $46 |
| Drip from the lid after a hot fill | Lid gasket compression set, or solid lid on a venting product | Lid gasket, or vented lid | $9 – $27 |
| Bottle bulging under pump draw-down | Solid lid with no vent path | Vented 6 in lid | $14 – $27 |
| Cannot connect a transfer hose | Buttress outlet, not pipe thread | S60 to camlock or NPT adapter | $12 – $58 |
| Flow too slow on viscous product | DN50 outlet where DN80 is needed | Specify DN80 at order; not a field change | — |
| Fitting binds after half a turn | Wrong thread form — stop immediately | Correct S60 or S100 adapter | $9 – $19 |
| Insects or algae in stored water | Vented lid on a storage unit, or no shade | Solid lid plus shade wrap | $14 – $27 |
Note that six of those nine are a gasket or a lid. In our experience the single most cost-effective thing a fleet owner can do is keep a strip of gaskets on a hook by the pump and replace them on a schedule rather than on failure.

A sensible spares kit, by fleet size
Parts are cheap and downtime is not. These are the holdings we would recommend, based on what customers actually run out of.
| Item | 1 – 10 totes | 11 – 50 totes | 51 – 200 totes |
|---|---|---|---|
| Valve gaskets, matched compound | 4 | 15 | 50 |
| Lid gaskets | 4 | 15 | 50 |
| DN50 butterfly valves | 1 | 3 | 10 |
| 6 in lids, solid | 2 | 6 | 20 |
| 6 in lids, vented | 1 | 3 | 10 |
| Outlet dust caps | 4 | 12 | 40 |
| S60 to garden hose adapters | 1 | 2 | 4 |
| Camlock adapters (A/C/F set) | 1 set | 2 sets | 5 sets |
| Approximate kit cost | ~$95 | ~$310 | ~$1,050 |
Short answer
- Replace gaskets at every wash, not at every failure
- Over half of all periodic test failures are a gasket
- Fit gaskets dry — no tape, no sealant, no grease
- Hand tight plus a quarter turn is the correct torque

Camlocks, buttress threads and the fitting that ruins an outlet
An IBC outlet is moulded into the bottle. Strip it and the whole bottle is scrap — which makes a four-dollar adapter the cheapest insurance in the catalogue.

What changed when we got our own reconditioner code
Before 2023 a UN re-marking took three weeks in somebody else's queue. Now it takes four days in ours. The interesting part is what the delay was actually costing.

What the 2.5-year retest actually catches
Three years of test bay records, sorted by failure mode. The periodic leakproofness test is not a formality, and what it finds is not what most people expect.

Tell us the product and we will specify the gasket.
Give us the liquid, the temperature and the outlet size. Gasket and valve compatibility is one of the few questions here with a single right answer, and getting it wrong costs two years of drips.
