Couplings, nuts, bolts & seals

The connective layer between regulators, hoses and rinse adapters: gas couplings, transfer couplings, fastening hardware and seals — supplied in the volumes that maintenance contracts and large installations need.

COUPLING · NUT · O-RING
Range

The parts every installation needs in volume.

Gas couplings & nipples

Connections between cylinder, regulator and line, per coupling type and thread.

Coupling

Transfer couplings

For transfer between tanks, kegs or line sections on larger installations.

Transfer

Nuts, bolts & stops

Fastening hardware in standard sizes, available in volume for maintenance stock.

Fastening

O-rings & seals

Wear parts per size and material, essential at every coupling or rinse adapter.

Seal

Adapters

Connects differing coupling types or thread sizes to each other.

Adapter
Why this is often the bottleneck

The wrong coupling, the wrong O-ring — the biggest source of leaks.

Most failures in a gas installation aren't in the regulator or hose itself, but in a mismatched coupling type, the wrong thread size, or a worn O-ring. This category is therefore just as critical to your installation's reliability as the regulators and hoses it connects.

Frequently asked questions

Couplings & fittings: questions and answers

How do I know which coupling type my installation uses?

The easiest way is to send a photo or the existing part number with your request. Coupling types differ in thread, diameter and locking mechanism, and are not always interchangeable without an adapter.

Do you also supply nuts, bolts and O-rings loose, in volume?

Yes — this is typically a category maintenance companies and installers order in larger quantities as replacement parts. Send us the size and material you need for a volume quote.
