Three replacement part products covering model-specific service kits for 1st stage overhaul, model-specific service kits for 2nd stage overhaul, and the General Service Kit providing common consumable components across multiple regulator models. Used in conjunction with the tools and lubricants in the Regulator Servicing category.
Model-Specific Service Kits
A service kit for a scuba regulator contains the consumable components replaced during an annual service: HP seat, IP seat or diaphragm, o-rings, spring, and any model-specific seals. Using the correct model-specific kit ensures all replacement parts match the original specifications — non-standard o-rings of incorrect durometer or dimension can cause IP instability, leaks, or premature wear.
The Service kit for single models 1st stage (SKU ND000030/42, 18–27 €) covers individual first stage models — Diana, Plutone, Mercurio, Giove, Minerva — with the variant determining which model’s components are included. The Service kit for single models 2nd stage (SKU ND000043/44/45/46, 14–23 €) covers second stage models including Venere and Andromeda variants.
General Service Kit
The Regulator General Service Kit (SKU 652028, 99 €) is a broad-coverage kit containing the most commonly replaced o-rings, seats, and seals across the Sopras Tek regulator range. It is appropriate for a service workshop maintaining multiple regulator models, or for divers who self-service several different regulators and prefer a single comprehensive parts stock rather than individual model-specific kits. It does not replace model-specific kits entirely — unique components for specific models are only available in the dedicated kits.
What to Look For
- Correct model identification: Service kits are model-specific. Confirm the exact model of your regulator — Diana, Plutone, Plutone ICE, Mercurio ICE, Giove ICE, Minerva for 1st stage; Venere, Andromeda for 2nd stage — before ordering. The SKU variant number identifies which model the kit is designed for.
- Annual kit usage: Even if a regulator appears to be functioning correctly, service kit components (HP seat, diaphragm) degrade with pressure cycling and time. Replacing them on schedule prevents in-water failures rather than responding to symptoms.
- General kit for multi-regulator workshops: The General Service Kit is the practical solution for anyone maintaining five or more regulators. Individual model-specific kits ordered one at a time are more expensive per kit than maintaining a general stock supplemented by specific kits for unusual components.
- Keep kits dry and sealed: Service kit o-rings and seats are precision components. Store sealed in original packaging in a dry, room-temperature environment. Exposure to UV, ozone, solvents, or elevated temperatures degrades o-ring elastomers before installation.
- Pair with Christo Lube: A service kit is used together with Christo Lube MCG 111 — the lubricant is not included in the kits. Order both simultaneously if your lubricant supply is running low.
Maintenance and Care
Service kits are single-use consumable items — components removed during service should be discarded rather than reused even if they appear undamaged. Reusing HP seats and diaphragms that have experienced pressure cycling creates an unknown failure risk. Keep unused kits in sealed packaging until the service date. For oxygen-service regulators, use only oxygen-compatible replacement parts and ensure Christo Lube MCG 111 is used throughout the service. Do not mix standard and oxygen-service parts in a single regulator build.
FAQ
How do I identify which service kit my regulator requires?
The model name is typically stamped or printed on the first stage body or second stage housing. For first stages, the model names in the Sopras Tek range are Diana, Minerva, Plutone, Mercurio, and Giove. For second stages, Venere and Andromeda are the primary models. The SKU variant on the product detail page maps to specific models. If you are unsure, the Sopras Tek service team can confirm the correct kit from a photo of the regulator and any visible serial or model markings.
Are replacement parts oxygen-compatible?
Standard service kits use materials appropriate for air and standard nitrox (up to 40% O₂) service. For regulators used on high-fraction oxygen mixes, oxygen-compatible o-rings and seats are required. Confirm with Sopras Tek whether the specific variant for your model is oxygen-rated before using it on a regulator intended for O₂ or high-nitrox service. The Christo Lube MCG 111 lubricant is always oxygen-compatible regardless of the kit used.
Can I use General Service Kit parts on any Sopras Tek regulator?
The General Service Kit contains common components that appear across multiple models — primarily standard-size o-rings, common HP seats, and shared consumables. It will not contain every model-specific component; for unique parts like a specific diaphragm geometry or a proprietary seat, the model-specific kit is required. The general kit is best used as a supplement to model-specific kits or as a stock for common components in a multi-regulator service environment.
Do I need a service kit for a new regulator?
New regulators do not require immediate servicing. A service kit is used at the annual service interval — typically one year or 100 dives after purchase for technical diving regulators. It is reasonable to order a service kit at the time of regulator purchase to have it available when the first service is due, particularly for models where kit availability might require lead time.
What tools do I need alongside a service kit?
In addition to a model-specific service kit, a complete first stage service requires: Christo Lube MCG 111, a flat or hexagonal adjustment tool (depending on model), an intermediate pressure gauge to verify IP after reassembly, and the Scuba service tool kit for spanner and pick work. The Regulator Servicing category stocks all of these. A service without an IP gauge cannot be confirmed as correctly set; the IP gauge is the minimum additional tool required beyond the kit itself.
