Drysuit Accessories

Valves, seals, ring systems, pockets and boots for keeping a drysuit sealed and working, from SiTech, Rolock, Halcyon, Santi, Fourth Element, Apeks, Otter and Beaver. Almost everything here is system specific rather than universal, so check what your suit is already fitted with before you order. If you are not sure what you have, talk to us first. We repair and service drysuits in house.

Check what your suit is fitted with

Drysuit valves, seals and dryglove rings are built as families that do not mix. SiTech and Rolock each use their own ring diameters and locking patterns, and designs change over time, so a part that fits one suit may not fit another from the same maker. Before ordering, work out which system is already on the suit. The name is usually moulded into the ring or the valve body. Then check the manufacturer specification for the part you want against what you have.

Valves

A drysuit uses an inflation valve, normally on the chest, and an exhaust or dump valve, normally on the upper arm. Both are sold as complete units and as individual components such as shells, skeletons, slides and internal port grommets, so it is easy to order half of what you actually need. Inflation valves also differ in hose connector, so check what your low pressure inflator hose fits before choosing one.

Seals and ring systems

Neck and wrist seals come in latex and silicone and in different shapes, and they are fitted in different ways depending on the suit. Silicone seals normally need a compatible ring system on the suit rather than being glued in. Dryglove rings follow the same rule: Rolock 90, the Rolock standard 1, 2 and 3 systems and the others each take their own drysuit side rings, glove side rings and O-rings. Match the system, not just the brand.

Pockets, boots and comfort items

Thigh and knife pockets, rock boots, hangers, hair savers and heating connectors are the day to day extras rather than sealing parts, but they are still not universal. Pockets attach differently depending on the suit, and boot sizing has to allow for a drysuit sock and undersuit layers underneath. Check the manufacturer sizing guide for the specific boot rather than working from your shoe size.

Fitting and repairs

Replacing seals, valves, zips and ring systems is workshop work. It decides whether the suit keeps water out, so we do not publish step by step instructions for it. Dive Rutland fits and repairs drysuits, including seal replacement, valve and P-valve fitting, zip replacement, boot and sock replacement and pressure testing. If a seal has torn, a valve has started weeping or you want a dryglove system installed, see Drysuit Repairs.

Frequently asked questions

Identify the system already fitted to the suit rather than the brand of the suit. Rolock 90, Rolock standard 1/2/3 and the other systems each use their own drysuit-side rings, glove-side rings and O-rings, and they do not mix.

The system name is usually marked on the ring itself. If you cannot find it, send us a photo of the cuff and we will tell you what you have before you order anything.

Treat them as specific to the make and model. Valves, seals and ring systems are designed as families, and even within one manufacturer the fittings change between generations, so a part that fits one suit will not necessarily fit another.

Check the manufacturer specification for the part against what is actually on your suit. If the listing does not confirm a match, ask us first rather than ordering and hoping.

We would not recommend it, and we deliberately do not publish instructions for it. These are the parts that keep water out of the suit, and a poor repair tends to show up on the dive rather than in the garage.

Dive Rutland repairs and services drysuits in house, including seal replacement, valve and P-valve fitting, zip replacement, boot and sock replacement and pressure testing. Send us the suit and we will do it properly.

Larger than your shoe size, but how much larger depends on the boot and on what you are wearing underneath. A drysuit sock plus undersuit layers takes up real space, and the amount varies between suits.

Check the manufacturer sizing guide for the specific boot, and if you are between sizes come and try them over the suit you actually dive. It is not a decision that works well from a chart.
