Type 17 (PF) is one of several quick-release coupling standards used across UK compressed air systems, and it's interchangeable with Schrader Standard and Rectus 17 fittings, which matters if you're adding to an existing airline network rather than starting from scratch. Before ordering, check what's already fitted on your compressor and tooling; the different PCL types (17, 19, 21, 25) aren't cross-compatible, and matching an adaptor to the wrong coupling standard won't connect.
Our Type 17 range covers standard couplings, adaptors, and twist couplings for higher-duty applications. BSPT and BSPP thread options are available depending on your existing pipework.
If you're unsure which coupling type your current system uses, check for a matching part number or bring an existing fitting for comparison rather than guessing from appearance alone.
Orders over £200 to England and Wales qualify for free delivery.
Frequently Asked Questions
Is Type 17 the same as Schrader Standard?
Type 17 PCL fittings are interchangeable with Schrader Standard and Rectus 17 couplings, so they'll connect to existing systems using either of those standards.
How do I know which PCL coupling type I already have?
Compare an existing fitting against the product photos, or check for a part number. The PCL types aren't cross-compatible, and appearance alone can be misleading between standards.
What's the difference between a standard coupling and a twist coupling?
A twist coupling locks with a rotating action rather than a straight push-fit, which is generally used for higher-duty or higher-pressure applications where added security matters.
Do you deliver Type 17 couplings and adaptors near me?
